Hello,
I'm currently using DLINk 704UP router. I configured the mIRC correctly I believe, as well as configuring the router. I think the problem lies in the router. If someone uses a similar router, that would be great if you could post how you have configured it (opening ports, etc..). Also, if there are any useful links and how-tos, please post the links as well. At this point in the game I'm willing to look at anything.
Thanks for the help
