Can someone explain the steps that I need to take in detail. I have Windows XP SP2 and a D-link router. I have opened the TCP ports 4000-4004 for DCC in the Windows XP firewall. Do I also need to change port settings in my router? If so, is it the same TCP 4000-4004? mIRC seems to want to connect to servers using ports 6665-6669. I've been able to get every other type of communications client working on my computer, but not mIRC. I'm a noob and can't figure this one out. Thanks in advance for any help you can provide.
