This can be required by some ISP providers. Select different WAN Connection Type will lead to different contents. Take the WAN connection type-DHCP for example, you can release and renew the WAN lease by pressing the buttons. You can enter a spoofed MAC address that causes your gateway networking stack to use that MAC address when communicating instead of the usual WAN MAC address, e.g., if the MAC address is 00:11:e3:df:66:95, this spoofed MAC address could be 00:11:e3:df:66:97 or any desired MAC address.

You can cancel an IP address lease by selecting it in the DHCP Client Lease Info list and then clicking the Force Available button. If you do so, you may have to perform a DHCP Renew on that PC, so that it can obtain a new lease. Fig. 16 Gateway\Network\Computers$

Options This page allows you to enable/disable some features of the Wireless Voice Gateway. Fig. 19 Gateway\Advanced\Options  WAN Blocking prevents others on the WAN side from being able to ping your gateway. With WAN Blocking enabled, your gateway will not respond to pings it receives, effectively “hiding” your gateway.  Ipsec PassThrough enables IpSec type packets to pass WAN  LAN. IpSec (IP Security) is a security mechanism used in Virtual Private Networks (VPNs).  PPTP PassThrough enables PPTP type packets to pass WAN  LAN. PPTP (Point to Point Tunneling Protocol) is another mechanism sometimes used in VPNs.  Remote Config Management makes the configuration web pages in your gateway accessible from the WAN side. Note that page access is limited to only those who know the gateway access password. When accessing your gateway from a remote location, your must use HTTP port 8080 and the WAN IP address of the gateway. For example, if the WAN IP address is 157.254.5.7, you would navigate to http://157.254.5.7:8080 to reach your gateway.  Multicast Enable enables multicast traffic to pass WAN LAN. You may need to enable this to see some types of broadcast streaming and content on the Internet.  UPnP Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically$

It is enabled by default and help in solving NAT related problems in client LAN side.

IP Filtering This page enables you to enter the IP address ranges of PCs on your LAN that you don’t want to have outbound access to the WAN. These PCs can still communicate with each other on your LAN, but packets designated to WAN addresses are blocked by the gateway. Fig. 20 Gateway\Advanced\IP Filtering$

$Chapter 2: WEB Configuration Illustrations contained in this document are for representation only. 41 3. MAC Filtering This page enables you to enter the MAC address of specific PCs on your LAN that you do not wish to have outbound access to the WAN. As with IP filtering, these PCs can still communicate with each other through the gateway, but packets they send to WAN addresses are blocked. Fig. 21 Gateway\Advanced\MAC Filtering$

$Chapter 2: WEB Configuration Illustrations contained in this document are for representation only. 42 4. Port Filtering This page allows you to enter ranges of destination ports (applications) that you don’t want your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked. For example, you could block access to worldwide web browsing (http = port 80) but still allow email service (SMTP port 25 and POP-3 port 110). To enable port filtering, set Start Port and End Port for each range, and click Apply. To block only one port, set both Start and End ports with the same value. Fig. 22 Gateway\Advanced\Port Filtering$

$Chapter 2: WEB Configuration Illustrations contained in this document are for representation only. 43 5. Forwarding For LAN  WAN communications, the gateway normally only allows you to originate an IP connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the destination port (application) matches one you specify. This page allows you to specify up to 10 such rules. For example, to specify that outsiders should have access to an FTP server you have running at 192.168.0.5, create a rule with that address and Start Port =20 and End Port =21 (FTP port ranges) and Protocol = TCP (FTP runs over TCP and the other transport protocol, UDP), and click Apply. This will cause inbound packets that match to be forwarded to that PC rather than blocked. As these connections are not tracked, no entry is made for them in the Connection Table. The same IP address can be entered multiple times with different ports. Fig. 23 Gateway\Advanced\Forwarding$

$Chapter 2: WEB Configuration Illustrations contained in this document are for representation only. 44 6. Port Triggers Some Internet activities, such as interactive gaming, require that a PC on the WAN side of your gateway be able to originate connections during the game with your game playing PC on the LAN side. You could use the Advanced-Forwarding web page to construct a forwarding rule during the game, and then remove it afterwards (to restore full protection to your LAN PC) to facilitate this. Port triggering is an elegant mechanism that does this work for you, each time you play the game. Fig. 24 Gateway\Advanced\Port Triggers Port Triggering works as follows. Imagine you want to play a particular game with PCs somewhere on the Internet. You make one time effort to set up a Port Trigger for that game, by entering into Trigger Range the range of destination ports your game will be sending to, and entering into Target Range the range of destination ports the other player (on the WAN side) will be sending to (ports your PC’s game receives on). Application programs like games publish this information in user manuals. Later, each time you play the game, the gateway automatically creates the forwarding rule necessary. This rule is valid until 10 minutes after it sees game activity stop. After 10 minutes, the rule becomes inactive until the next matched outgoing traffic arrives. For example, suppose you specify Trigger Range from 6660 to 6670 and Target Range from 113 to 113. An outbound packet arrives at the gateway with your game-playing PC source IP address 192.168.0.10, destination port 666 over TCP/IP. This destination port is within the Trigger destined for port 113 to your game-playing PC at 192.168.0.10. You can specify up to 10 port ranges on which to trigger.$

DMZ Host Use this page to designate one PC on your LAN that should be left accessible to all PCs from the WAN side, for all ports. For example, if you put an HTTP server on this machine, anyone will be able to access that HTTP server by using your gateway IP address as the destination. A setting of “0” indicates NO DMZ PC. “Host” is another Internet term for a PC connected to the Internet. Fig. 25 Gateway\Advanced\DMZ Host$
