The two radio transceivers can work simultaneously, For information on configuring the wireless radio band, see “Wireless Network Configuration” on page 28.Grounding LugA one-hole grounding lug is provided on the back of the chassis to connect the device to earth ground (see Figure 4). To ground the device before connecting power, you connect a grounding cable to earth ground and then attach the cable to the lug on the rear of the chassis.Power adapterUSB host modulegrounding lugAntenna A Antenna B
Back Panel 9Antennae TypesThe SSG 20-WLAN device supports three types of custom-built radio antennae:Diversity antennae — The diversity antennae provide 2dBi omnidirectional coverage and a fairly uniform level of signal strength within the area of coverage and are suitable for most installations. this type of antennae are shipped with the device.External omnidirectional antenna — The external antenna provides 2dBi omnidirectional coverage. Unlike diversity antennae, which function as a pair, an external antenna operates to eliminate an echo effect that can sometimes occur from slightly delayed characteristics in signal reception when two are in use. External directional antenna — The external directional antenna provides 2dBi unidirectional coverage and is well suited for such places as hallways and outer walls (with the antenna facing inward).Universal Serial Bus (USB) Host ModuleThe slot labeled USB on the back panel of an SSG 20 device implements a host-only USB 1.1 host module for a USB device adapter or USB flash key, as defined in the CompactFlash Specification published by the CompactFlash Association. When the USB storage device is installed and configured, it automatically acts as a secondary storage device. The USB host module allows file transfers, such as device configurations, user certifications, and update version images between an external USB flash key and the internal flash storage located in the security device. The USB host module supports USB 2.0 specification at either low-speed (1.5M) or full-speed (12M) file transfer.To use a USB flash key to transfer files between the device, perform the following steps:1. Insert the USB flash key into the USB host module on the security device.2. Save the files from the USB flash key to the internal flash storage on the device with the save { software | config | image-key } from usb filename to flash CLI command.3. Before removing the USB flash key, stop the host module with the exec usb-device stop CLI command.4. It is now safe to remove the USB flash key.If you want to delete a file from the USB flash key, use the delete file usb:/filename CLI command.If you want to view the saved file information on the USB flash key or internal flash storage, use the get file info CLI command.

Ensure that enclosed racks have fans and louvered sides.Correct these hazardous conditions before any installation: moist or wet floors, leaks, ungrounded or frayed power cables, or missing safety grounds. Equipment Rack InstallationYou can front-mount an SSG 20 device into a standard 19-inch equipment rack. The device is shipped with mounting brackets installed.To front-mount an SSG 20 device, you need a number 2 phillips screwdriver (not provided) and four screws that are compatible with the equipment rack (not provided).To install an SSG 20 device onto a rack:1. Align the rack mount ears to the device.2. Place the screws in the holes and use a phillips screwdriver to secure them.3. Mount the device on the rack with the provided screws.4. Plug the power supply into the power outlet.Connecting the Interface Cable to a DeviceTo connect the interface cable to a device, perform the following steps:1. Have ready a length of the type of cable used by the interface.2. Insert the cable connector into the cable-connector port on the interface faceplate.3. Arrange the cable as follows to prevent it from dislodging or developing stress points:a. Secure the cable so that it is not supporting its own weight as it hangs to the floor.b. Place any excess cable out of the way in a neatly coiled loop.c. Use fasteners to maintain the shape of the cable loops.
Connecting the Power 13Connecting the PowerTo connect the power to a device, perform the following steps:1. Plug the DC connector end of the power cable into the DC power receptacle on the back of the SSG device.2. Plug the AC adapter end of the power cable into an AC power source.Connect the Device to a NetworkAn SSG 20 device provides firewall and general security for networks when it is placed between internal networks and the untrusted network. This section describes the following:Connecting the device to an untrusted networkConnecting the device mini PIMs to an untrusted NetworkConnecting the device to an internal network or workstationConnect an SSG 20 Device to an Untrusted NetworkYou can connect your SSG 20 device to the untrusted network in one of the following ways:Connecting Ethernet PortsConnecting Serial (AUX/Console) PortsConnecting Ethernet PortsTo establish a high-speed connection, connect the provided Ethernet cable from the Ethernet port marked 0/0 on an SSG 20 device to the external router. This Ethernet port (0/0) is assigned to the ethernet0/0 interface, which is by default bound to the Untrust security zone. The device autosenses the correct speed, duplex, and MDI/MDIX settings.Connecting Serial (AUX/Console) PortsYou can connect to the untrusted network with an RJ-45 straight through serial cable and external modem.WARNING: We recommend using a surge protector for the power connection.WARNING: Make sure that you do not inadvertently connect the Console, AUX, or Ethernet ports on the device to the telephone outlet.
SSG 20 Hardware Installation and Configuration Guide14 Connect the Device to a NetworkConnect an SSG Device to an Untrusted NetworkFigure 5 shows basic network cabling connections for a device. This figure shows two blank PIMs and the 10/100 Ethernet ports are cabled as follows:The port labeled 0/0 (ethernet0/0 interface) is connected to the untrust network.The port labeled 0/1 (ethernet0/1 interface) is connected to a switch that connects workstations on the DMZ LAN.The ports labeled 0/2 through 0/4 (ethernet0/2 through ethernet0/4 interfaces) are connected to a switch that connects workstations to the trusted network.The console port is connected to a serial terminal for management access.Figure 5: Basic Networking ExampleConnect Mini PIMs to an Untrusted NetworkThis section explains how to connect the device mini PIMs to an untrusted network.Connecting the ADSL2/2+ Mini PIMConnect the provided ADSL cable from the ADSL2/2+ mini PIM to your telephone outlet. The ADSL port on the Annex A version of the device uses an RJ-11 connector, while the Annex B version uses an RJ-45 connector. In the case of Annex B models, the cable you connect from the ADSL port to the telephone outlet is identical in appearance and wiring to a straight through 10 Base-T Ethernet cable.Connecting Splitters and MicrofiltersA signal splitter divides the telephone signal into low-frequency voice signals for voice calls and high-frequency data signals for data traffic. Your service provider usually installs the splitter as part of the equipment that connects your site telephone lines to the provider network.There are also splitters that you may be able to install yourself, depending upon your service-provider equipment.

Default Device Settings 21Default Device SettingsThis section describes the default settings and operation of an SSG 20 device.Table 5 describes the default zone bindings for ports on the devices.Table 5: Default Physical Interface to Zone BindingsA bridge group, bgroup, is designed to allow network users to switch between wired/wireless traffic without having to reconfigure or reboot the device. By default, the ethernet0/2—ethernet0/6 interfaces, labeled as port 0/2—0/6 on the device, are grouped together as the bgroup0 interface, have the IP address 192.168.1.1/24, and are bound to the Trust security zone. You can configure up to four bgroups.If you want to set an Ethernet or wireless interface into a bgroup, you must first make sure that the Ethernet or wireless interface is in the Null security zone. Unsetting the Ethernet or wireless interface that is in a bgroup places the interface in the Null security zone. Once assigned to the Null security zone, the Ethernet interface can be bound to a security zone and assigned a different IP address.To unset ethernet0/3 from bgroup0 and assign it to the Trust zone with a static IP address of 192.168.3.1/24, do the following:unset interface bgroup0 port ethernet0/3set interface ethernet0/3 zone trustset interface ethernet0/3 ip 192.168.3.1/24savePort Label Interface ZoneConsole N/A N/AAUX serial0/0 Null10/100 Ethernet ports:0/0 ethernet0/0 Untrust0/1 ethernet0/1 DMZbgroup00/20/30/4bgroup0 (default IP address is 192.168.1.1/24)ethernet0/2ethernet0/3ethernet0/4TrustWAN Mini PIM ports: (x = mini PIM slot, 1 or 2)ADSL2/2+ (Annex A) adsl(x/0) UntrustADSL2/2+ (Annex B) adsl(x/0) UntrustT1 serial(x/0) UntrustE1 serial(x/0) UntrustISDN bri(x/0) UntrustV.92 serial(x/0) Null

SSG 20 Hardware Installation and Configuration Guide24 Basic Device ConfigurationSetting the Date and TimeThe time set on an SSG 20 device affects events such as the setup of VPN tunnels. The easiest way to set the date and time on the device is to use the WebUI to synchronize the device system clock with the workstation clock.WebUI1. Configuration > Date/Time: Click the Sync Clock with Client button.A pop-up message prompts you to specify if you have enabled the daylight saving time option on your workstation clock.2. Click Yes to synchronize the system clock and adjust it according to daylight saving time or click No to synchronize the system clock without adjusting for daylight saving time.You can also use the set clock CLI command in a Telnet or Console session to manually enter the date and time for the SSG device.Bridge Group InterfacesBy default, the SSG 20 device has Ethernet interfaces ethernet0/2—ethernet0/4 grouped together in the Trust security zone. Grouping interfaces sets interfaces in one subnet. You can unset an interface from a group and assign it to a different security zone. Interfaces must be in the Null security zone before they can be assigned to a group. To place a grouped interface in the Null security zone, use the unset interface interface port interface CLI command.The SSG 20-WLAN devices allow Ethernet and wireless interfaces to be grouped under one subnet.To configure a group with Ethernet and wireless interfaces, do the following:unset interface bgroup0 port ethernet0/3unset interface bgroup0 port ethernet0/4set interface bgroup1 port ethernet0/3set interface bgroup1 port ethernet0/4set interface bgroup1 port wireless0/2set interface bgroup1 zone DMZset interface bgroup1 ip 10.0.0.1/24saveNOTE: Only wireless and Ethernet interfaces can be set in a bridge group.

SSG 20 Hardware Installation and Configuration Guide26 Basic Device ConfigurationDefault RouteThe default route is a static route used to direct packets addressed to networks that are not explicitly listed in the routing table. If a packet arrives at the device with an address that the device does not have routing information for, the device sends the packet to the destination specified by the default route.WebUINetwork > Routing > Routing Entries > New: Enter the following, then click OK:Network Address/Netmask: 0.0.0.0/0.0.0.0Gateway: (select)Interface: serial1/0 (select)Gateway IP Address: ip_addrCLIset route 0.0.0.0/0 interface serial1/0 gateway ip_addrsaveManagement Interface AddressThe Trust interface has the default IP address 192.168.1.1/24 and is configured for management services. If you connect the 0/2—0/4 port on the device to a workstation, you can configure the device from a workstation in the 192.168.1.1/24 subnetwork using a management service such as Telnet.You can change the default IP address on the trust interface. For example, you might want to change the interface to match IP addresses that already exist on your LAN. Backup Untrust Interface ConfigurationThe SSG 20 device allows you to configure a backup interface for untrust failover. To set a backup interface for untrust failover, perform the following steps:1. Set the backup interface in the Null security zone with the unset interface interface [ port interface ] CLI command.2. Bind the backup interface to the same security zone as the primary interface with the set interface interface zone zone_name CLI command.NOTE: The primary and backup interfaces must be in the same security zone. One primary interface has only one backup interface, and one backup interface has only one primary interface.

To use the wireless local area network (WLAN) capabilities on the device, you must configure at least one Service Set Identifier (SSID) and bind it to a wireless interface.Figure 9 shows the default configuration for the SSG 20-WLAN device.NOTE: If you are operating the SSG 20-WLAN device in a country other than the United States or Japan, then you must use the set wlan country-code command before a WLAN connection can be established. This command sets the selectable channel range and transmit power level.
SSG 20 Hardware Installation and Configuration Guide28 Wireless ConfigurationFigure 9: Default SSG 20-WLAN ConfigurationBy default, the wireless0/0 interface is configured with the IP address of 192.168.2.1/24. All wireless clients that need to connect to in the Trust zone must have an IP address in the wireless subnetwork. You can also configure the device to automatically assign IP addresses in the 192.168.2.1/24 subnetwork to your devices with DHCP.By default, the wireless0/1 - wireless0/3 interfaces are defined as Null and do not have IP addresses assigned to them. If you want to use any of the other wireless interfaces, you must configure an IP address for it, assign an SSID to it, and bind it to a security zone.For more information about WLANs, refer to “Wireless Interface” in the Concepts and Examples ScreenOS Reference Guide.Wireless Network ConfigurationWireless networks consist of names referred to as Service Set Identifiers (SSIDs). Specifying SSIDs allows you to have multiple wireless networks reside in the same location without interfering with each other. An SSID name can have a maximum of 32 characters. If a space is part of the SSID name string, then the string must be enclosed with quotation marks. Once the SSID name is set, more SSID attributes can be configured.The SSG 20-WLAN device allows you to create up to 16 SSIDs, but only 4 of them can be used simultaneously. You can configure the device to use the 4 SSIDs on either one of the transceivers or split the use on both. For example, 3 SSIDs assigned to WLAN 0 and 1 SSID assigned to WLAN 1. Use the set interface wireless_interface wlan { 0 | 1 | both } CLI command to set the radio transceivers on the SSG 20-WLAN device.To set the SSID name netscreen open, allow the SSID to be open to all users, bind the SSID to the wireless0/0 interface, and use both radio transceivers, do either of the following: AUX 0/010/100AUX 0/010/1000/010/1000/010/1000/010/100LINKSTATUSPOWERPIM 2PIM 1b/g802.11aWLANSSG 2012InternetTrust Zonebgroup0 (ethernet0/2 — ethernet0/4)wireless0/0 (192.168.2.1/24)ConsoleDMZ Zone

Refer to the Concepts & Examples ScreenOS Reference Guide for configuration examples, SSID attributes, and CLI commands relating to wireless security configurations.Mini PIM ConfigurationThis section explains how to configure the mini physical interface modules (PIMs):“Asymmetrical DSL (ADSL) 2/2+ Interface” on this page“The ISDN Interface” on page 34“The T1 Interface” on page 35“The E1 Interface” on page 36“The V.92 Modem Interface” on page 37Asymmetrical DSL (ADSL) 2/2+ InterfaceYour network uses the ADSL2/2+ interface adslx/0, with x representing the mini PIM slot (1 or 2), on the device to connect to the service provider’s network through an Asynchronous Transfer Mode (ATM) virtual circuit. You can configure additional virtual circuits by creating ADSL2/2+ subinterfaces. For more information, see “Virtual Circuits to an ADSL2/2+ Interface” on page 31.In the WebUI, navigate to the Network > Interfaces > List page to see a list of the current interfaces on the device. If you are using a Telnet or Console session, enter the get interface CLI command. You should see that the adslx/0 interface is bound to the Untrust zone.Authentication EncryptionOpen Allows any wireless client to access the deviceShared-key WEP shared-keyWPA-PSK AES/TKIP with Pre-shared keyWPA AES/TKIP with key from RADIUS serverWPA2-PSK 802.11i compliant with a pre-shared keyWPA2 802.11i compliant with a RADIUS serverWPA-Auto-PSK Allows WPA and WPA2 type with pre-shared keyWPA-Auto Allows WPA and WPA2 type with RADIUS server802.1x WEP with key from RADIUS server
Mini PIM Configuration 31If you are using the ADSL2/2+ interface to connect to the service provider’s network, you must configure the adsl(x/0) interface. To do this, you must obtain the following information from your service provider:Virtual Path Identifier and Virtual Channel Identifier (VPI/VCI) valuesATM Adaptation Layer 5 (AAL5) multiplexing method, which can be one of the following:Virtual Circuit-based multiplexing, in which each protocol is carried over a separate ATM virtual circuit Logical Link Control (LLC) encapsulation, which allows several protocols to be carried on the same ATM virtual circuit (the default multiplexing method)Username and password assigned by the service provider for connection to the service provider’s network using either Point-to-Point Protocol over Ethernet (PPPoE) or Point-to-Point Protocol over ATM (PPPoA)Authentication method, if any, provided for the PPPoE or PPPoA connectionOptionally, a static IP address and netmask value for your networkVirtual Circuits to an ADSL2/2+ InterfaceTo add virtual circuits, you create subinterfaces to the ADSL2/2+ interface. You can create up to 10 ADSL2/2+ subinterfaces. For example, to create a new subinterface named adsl1/0.1 bound to the user-defined zone named Untrust:WebUINetwork > Interfaces > New ADSL Sub-IF: Enter the following, click Apply:Interface Name: adsl1/0.1VPI/VCI: 8/35Zone Name: Untrust (select)CLIset interface adsl 1/0.1 pvc 0 35 zone UntrustsaveYou need to configure an ADSL 2/2+subinterface in the same way as the main ADSL2/2+ interface, including setting the VPI/VCI values, as described in “Connecting the ADSL2/2+ Mini PIM” on page 12. You configure an ADSL2/2+ subinterface independently of the main ADSL2/2+ interface; that is, you can configure a different multiplexing method, VPI/VCI, and PPP client on the subinterface than on the main ADSL2/2+ interface. You can also configure a static IP address on a subinterface, even if the main ADSL2/2+ interface does not have a static IP address. Note that a subinterface and the main ADSL2/2+ interface have to use the same VPI/VCI values if one interface is configured for PPPoA and the other for PPPoE and they both use LLC multiplexing.
SSG 20 Hardware Installation and Configuration Guide32 Mini PIM ConfigurationVPI/VCI and Multiplexing MethodYour service provider assigns a VPI/VCI pair for each virtual circuit connection. For example, you may receive the VPI/VCI pair 1/32, which means a VPI value of 1 and a VCI value of 32. These values must match the values that the service provider has configured on the subscriber’s side of the Digital Subscriber Line Access Multiplexer (DSLAM).To configure the VPI/VCI pair 1/32 on the adsl1/0 interface:WebUINetwork > Interfaces > Edit (for the adsl1/0 interface): Enter 1/32 in the VPI/VCI field, click Apply.CLIset interface adsl1/0 pvc 1 32saveBy default, the device uses LLC-based multiplexing for each virtual circuit. To configure the VPI/VCI 1/32 on the adslx/0 interface and use LLC encapsulation on the virtual circuit:WebUINetwork > Interfaces > Edit (for the adsl1/0 interface): Enter the following, click Apply:VPI/VCI: 1 / 32Multiplexing Method: LLC (selected)CLIset interface adsl1/0 pvc 1 32 mux llcsavePPPoE or PPPoAAn SSG 20 device includes both PPPoE and PPPoA clients to connect to the service provider’s network over the ADSL link. PPPoE is the most common form of ADSL encapsulation and is intended for termination on each host on your network. PPPoA is used primarily for business class-service as PPP sessions can be terminated on the device. To allow the device to connect to the service provider’s network, you need to configure the username and password assigned by the service provider. The configuration for PPPoA is similar to the configuration for PPPoE.NOTE: The device supports only one PPPoE session on each virtual circuit.
Mini PIM Configuration 33To configure the user name roswell and password area51 for PPPoE and bind the PPPoE configuration to the adsl1/0 interface:WebUINetwork > PPP > PPPoE Profile> New: Enter the following, click OK:PPPoE Instance: poe1Bound to Interface: adsl1/0 (select)Username: roswellPassword: area51CLIset pppoe name poe1 username roswell password area51set pppoe name poe1 interface adsl1/0saveThere are other PPPoE or PPPoA parameters that you can configure on the device, including method of authentication (by default, the device supports either Challenge Handshake Authentication Protocol or Password Authentication Protocol), idle timeout (default is 30 minutes), and so on. Ask your service provider if there are additional PPPoE or PPPoA parameters that you need to configure to enable proper communications with the service provider’s server.Static IP Address and NetmaskIf your ISP gave you a specific, fixed IP address and netmask for your network, then configure the IP address and netmask for the network and the IP address of the router port connected to the device. You need to also specify that the device is to use the static IP address. (Typically, the device acts as a PPPoE or PPPoA client and receives an IP address for the ADSL interface through negotiations with the PPPoE or PPPoA server.)You need to configure a PPPoE or PPPoA instance and bind it to the adsl1/0 interface, as described in “PPPoE or PPPoA” on page 32. Make sure that you select Obtain IP using PPPoE or Obtain IP using PPPoA and the name of the PPPoE or PPPoA instance.To configure the static IP address 1.1.1.1/24 for the network:WebUINetwork > Interfaces > List > Edit (for the adsl1/0 interface): Enter the following, click Apply:IP Address/Netmask: 1.1.1.1/24Static IP: (select)CLIset interface adsl1/0 ip 1.1.1.1/24set pppoe name poe1 static-ipsaveorset interface adsl1/0 ip 1.1.1.1/24set pppoa name poa1 static-ipsave
SSG 20 Hardware Installation and Configuration Guide34 Mini PIM ConfigurationTo use Domain Name System (DNS) for domain name and address resolution, the computers in your network need to have the IP address of at least one DNS server. If the device receives an IP address for the ADSL2/2+ interface through PPPoE or PPPoA, then it also automatically receives IP addresses for the DNS server(s). If the computers in your network obtain their IP address(es) from the DHCP server on the device, then the computers also obtain these DNS server addresses. If you assign a static IP address to the ADSL2/2+ interface, then the service provider must give you the IP address(es) of the DNS server(s). You can either configure the DNS server address on each computer in your network or configure the DHCP server on the Trust zone interface so that it provides the DNS server address to each computer.To configure the DHCP server on the bgroup0 interface to provide the DNS server address 1.1.1.152 to computers in your network:WebUINetwork > DHCP > Edit (for the bgroup0 interface) > DHCP Server: Enter 1.1.1.152 for DNS1, click Apply.CLIset interface bgroup0 dhcp server option dns1 1.1.1.152saveFor more information about configuring the ADSL and ADSL2/2+ interfaces, refer to the Concepts & Examples ScreenOS Reference Guide.The ISDN InterfaceIntegrated Services Digital Network (ISDN) is a set of standards for digital transmission over different media created by the Consultative Committee for International Telegraphy and Telephone (CCITT) and International Telecommunications Union (ITU). As a dial-on-demand service, it has fast call setup and low latency as well as the ability to carry high-quality voice, data, and video transmissions. ISDN is also a circuit-switched service that can be used on both multipoint and point-to-point connections. ISDN provides a service router with a backup connection for network interfaces. The ISDN interface is usually configured as the backup interface of the Ethernet interface to access external networks.To configure the ISDN interface, do either of the following:WebUINetwork > Interfaces > Edit (bri1/0): Enter or select the applicable option value, then click OK.BRI Mode: Dial Using BRIPrimary Number: 123456WAN Encapsulation: PPPPPP Profile: isdnprofileCLIset interface bri1/0 dialer-enableset interface bri1/0 primary-number "123456"set interface bri1/0 encap ppp

You can configure policies that direct the device to permit outside computers to start specific kinds of sessions with your computers. For information about creating or modifying policies, refer to the Concepts and Examples ScreenOS Reference Guide.The SSG 20 device provides various detection methods and defense mechanisms to combat probes and attacks aimed at compromising or harming a network or network resource:ScreenOS SCREEN options secure a zone by inspecting, and then allowing or denying, all connection attempts that require crossing an interface to that zone. For example, you can apply port scan protection on the Untrust zone to stop a source from an remote network from trying to identify services to target for further attacks.The device applies firewall policies, which can contain content filtering and intrusion detection and prevention (IDP) components, to the traffic that passes the SCREEN filters from one zone to another. By default, no traffic is permitted to pass through the device from one zone to another. To permit traffic to cross the device from one zone to another, you must create a policy that overrides the default behavior.NOTE: The V.92 interface does not work in transparent mode.
