This page allows you to specify up to 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.

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.

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
Start Port
and
Tigger End Port
the range of destination ports your game will be sending to, and
entering into
Target Start Port
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.
e.g., 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

7. 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. e.g., 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.

8. RIP (Routing Information Protocol) Setup
This feature enables the gateway to be used in small business situations where more than one LAN (local
area network) is installed. The RIP protocol provides the gateway a means to “advertise”
available IP
routes to these LANs to your cable operator, so packets can be routed properly in this situation.
Your cable operator will advise you during installation if any setting changes are required here.
