Connecting to a server at home on a router

It's late at night right now, and questions are popping in to my head that I do not have the motor skills to search for right now.....so I'm asking them here.

I have a home network and with winsock and all that, you connect to other computers through sockets and using an IP address to connect, right? Well, when I figure out my internet IP (I have cable, so my IP rarely changes...if it all) via http://www.whatismyip.com/ or some other site like that, that gives me my ip all fine and dandy.....but how do I make a winsock program that I can put on a friend's computer that could connect to my computer through my router and everything?

you dont need to worry about your router unless it is interfering with ports... otherwise just use the standard operation of sockets that you have read about.

He's doesn't have a router, he actually has a router/nat box if he has cable. Therefore, packets need to be forwarded. Go need to go to your "router"'s configuration, and forward port whatever to your internal ip (probably like 192.168.1.100)

this is great...i don't know the login info for my damn router....i'll have to make a bruteforce hacking program now, great, this could take a while

ahahahahha

that was easier to figure out then i thought it would be....

lol, you could've just downloaded Brutus.

k, well, i got my P2P program working now. I spent 2 hours on it and am happy with the results. I can connect to myself both by 127.0.0.1 and also my web IP address. However, when I gave the client program to a friend to connect to my server, it can't find the server for some reason, any reason why it might do this? defeats the purpose of my p2p program if people have to set up their routers just to connect to my server....seems kinda stupid

by default, routers like your allow outbound connections, just not inbound. So if, on yours, you forward the port, other people won't have any problem getting on.
