i'm trying to build a small messenger application, peer-to-peer, very simple, using window sockets.
the thing is that is working when i'm using a real ip.
but when i test it from a lan, i cannot connect to the other peer if i'm passing through a proxy.
is there a posibility to program the application to work through a proxy?
if i'm in a lan, and i have a c application which start a listening server on any port (3333 for example), can i access this port from outside?
sorry if my questions seem stupid, but i don't know so much about networks...
so i would appreciate any suggestion, explication, etc...
