internet file transfer
Posted on 2006-06-19
I was just wondering how yahoo makes it possible for com1 and com2 to connect to each other? The reason I am asking this is because I have created small network application, which main purpose is to transfer a file from com1 to com2, and unless I open/forward the port on com2, com1 is unable to connect to it. Both PCs use same mini DLS routers.
Yahoo has no problem at all when I do the same task because it creates direct connection but, I have no idea how... does it use some sort of network address translation internally or there is something else to it..?
