Telnet Troubles

I have set up a telnet server, which would allow people to connect to it. I can connect to it by using localhost and my internal ip address, and all my other computers connected in my network can also connect via my internal ip address. I have a LinkSys Router, and Norton firewall, and I am trying to get people to connect to me but they can't.

When I check my Ip address is IPCONFIG it tells me my internal ip address when i go to http://www.ipchicken.com it tells me a totally diffrent one. When other people are connecting how would they connect?

 

They will not be able to connect to you using your private IP address. You will have to instruct the router to pass through (port forward) the public address to a specific internal machine (the one where you have telnet running).

On the linksys router under APPLICATIONS & GAMING you have a port range forward table. Here you tell the router to forward the TELNET port usually port 23 to a specific internal IP address. You tell your friends to TELNET to the address that you get from ipchicken.com.

Concerns.........If you do not use static IP addresses when your IP address changes for your cable/dsl modem or any of your internal addresses change...then your telnet access will fail.

 

Beat me to the punch Jcon. Anyway, I use the linksys WRT54G line of routers, and I user the exact method he describes so that I can host Ventril0 and TeamSpeak servers off my box. It's all about figuring which ports are used, and forwarding them to the correct internal IP. And yeah, if you have a Dynamic IP, you will have problems. But most cable users have Static external IPs.

EDIT: The reason you see your internal IP when you IPCONFIG is because that is the IP address assigned to you by your DHCP server, in this case your router. Your external IP is stopped at your router.
