Firstly, I am sorry to irritate you with another topic about hosting problems. I have looked around for ways to solve my problem for several weeks, and came out unsuccesful.

Basically, whenever I host I ping to others and they can't join.
Many people say this is because of a firewall, and I do have one. I have tried disabling it and then hosting, but still I pinged. I have cable, and a router (Called HP Gateway or something). I am sharing the cable and router with my dad's computer as well. Feel free to ask me any questions that you think may be useful in the process of solving this problem, and once again, I apologize for irritating some of you into doing research on this problem, but hosting is an important part of playing jj2 for me. Without hosting, I cant beta test my levels online, host duels or levels and that kind of stuff. Anyways, thanks in advance and hope this gets solved.
