Hey all,

I just completed a job where they wanted to go wireless and switch ISP. Well, I setup all the new ISP WAN info in the router (WRT54G Linksys wireless router), and set the telnet port (23) to the address of their UNIX server. They use a software called Medical Manager, and we have no problems what so ever telnetting to this server from inside the network. The problem I am having, is that it wont telnet from the WAN address. Let me make a small diagram:

Router IP: 192.168.2.1
UNIX SERVER: 192.168.2.99


The telnet port is forwarded to .99, and I even turned on DMZ to .99, still no telnet to the wan address. The WAN is pingable from any location I am at, and I have a remote connection to one station there at the office. Has anyone ever expeirienced this before?

BTW: I have updated the router to the newest firmware.

Perhaps the ISP blocks inbound connections to port 23.
Open a different port on the router and use Port Forwarding
to get to the server port 23. Hope that helps.

Found out the problem. I knew I setup everything right. But their Unix server was using a default gateway of 192.168.2.255. I was like....255! what!? lol. So I changed it to the right gateway and everything is good.
