nOOb question: server behind router

Hi guys.

I've got this LAN server, that I want to put on the internet. The thing is, it's behind a router; When trying to access it from the outside, I'd probably have to type in the IP address of my router, but how do I tell the router what computer in the LAN I want to "get in touch" with?

Do I do that as a client, or do I have to cinfigure the router?
If I have to configure the router, how do I, as a client, tell the router which one of the servers I want to connect to?

Thanks for reading!

Torst.

I don't know much about routers, but you'll most likely have to do some port forwarding. Try typing the IP address of your computer into your browser. This should bring you to the control panel for your home network (your username and password are probaly "admin"). You might be able to figure it out through there. Sorry I couldn't be of more help.

Actually Tomk is right on target.

Your external IP will provide the content for the requests, ut in order to do that you need to forward the ports you require (80 for http, commonly) to the back end server.

How that exactly is done, depends on your router model.

On my Unix firewall the line in my nat config is something like
redirect_port tcp <server_IP>:80 80

YMMV.

Cheers.

Thanks a lot for that guys.
