How Do I Connect?

Hi I was wondering if it is possible to connect to a computer that is on a "HOME NETWORK"?

Explenation: I built an IRC Program and i'm putting server on a computer that is on my home network.I go to www.cmyip.com and it gives me the internet ip of the computer but when i put it in on my client program i can't seem to connect.

If you don't understand here's what i mean.

1) Put Main Server on Computer that is on a home network
2) got Internet IP of the computer that is on a home network from (www.cmyip.com)
3) im at my friends house and i try connecting to the server with client program using the Same IP from (www.cmyip.com) but fails to connect.
4) i get extreamly pist off! lol

Don't worry i'm no noob so please don't ask me stupind questions for i'm used to working with networks.

And
5)Excuse my English I was in a rush

You're most likely behind a router (either a separate box or your modem is also a router). You need to forward the port you're using for IRC to the computer the server is running on. Depending on the router, you may also have to give that computer a static internal address.

I assume that when you run the client on one of ythe computers in the network it works - otherwise you have other problerms you have to clear up first. (Like punching a hole in the firewall on the server or turning the firewall off.)

Ok ill try that. I do have a firewall and that may be the case. I also have another question. How would i use vb to get the Internet IP addresse instead of getting network IP addresse?

You could use VB (Winsock1.LocalIP, for instance), but ipconfig (run from a cmd window) will tell you what it is, and if you make it static (Control Panel/Network Connections/<your connection>/Properties/Internal Protocol (TCP/IP)/Properties/Use the following IP address - you'll have to set the DNS addresses too - you can find them in your router) it won't change. (Choose one outside the range of your router's DHCP server, and not ending in .0 or .255)

I'm going to need someone to help me because i did what you said about the connecting part but doesnt seem to work do you have msn?

Ok i tryed turning of firewalls on pc running server but didnt work. if i plug the internet directly to pc running server it works fine. Is it because my administrator computer (computer sharing internet) is running firewall?

My network is not big its two computer connected with a crosscable no routers.All is configured correctly but im thinking maybe its administrator firewall that may be blocking is that possible?
