====Question or Symptom====<br />
DSL customer is using private IP space on their lan and using NAT on<br />
their Flowpoint router. This allows traffic from their private IP space<br />
to be routed to the Internet, and the Flowpoint router will give its IP<br />
address as the IP address for all traffic leaving through the router.<br />
The problem comes in when the user has an application, such as a web<br />
server, running on the LAN that they want visible from the outside<br />
world. My experience was with a gamer who needed people to have an IP<br />
address for his machine so they could join games he was hosting.<br />
<br />
<br />
====Resolution====<br />
Find out if the application always uses the same TCP or UDP port. If so, port<br />
forwarding may solve the problem. It works by telling the router to pass any<br />
traffic addressed to the routers IP AND a certain port to a specific IP address<br />
on the Lan. This machine's IP address will have a private space IP address that<br />
would ordinarily not be available from the outside world.<br />
<br />
Procedure is look up the client's router's password in and WAN IP in x-mod. <br />
Then telnet to the router, login, and issue the command for port forwarding:<br />
<br />
system addserver <LAN server IP address> <protocol> <port><br />
<br />
save<br />
<br />
Example:<br />
<br />
system addserver 192.168.254.2 tcp 2346<br />
save<br />
<br />
You must type "save" if you want this configuration to still be in place <br />
when the router is rebooted.<br />
