YES PLEase. I'm having the exact same problem, cept im running on JA+ mod, which really shouldn't make a difference. My IP changes every time i reconnect, but that really shouldn't be the problem either.
NOBODY, not even me, can see my freaking server, and I've tried everything on my own-- i set the net_forcenonlocal to 1, did absolutely nothing. I can't set the net_ip to anything but localhost without it completely not working.
I've set the port to 21000, that's default, and dedicated to 2, and set the com_hunkmegs (whatever that is) to 64. That is all the defaults for my dedicated server.
SOMEbody please help us, come on.
EDIT: I forgot to mention, i'm using jedi academy, but it really has the exact same problem as jk2 does, they use the same engine.
EDIT: Also, I work behind a router, but my network admin insists that there is no interference by the router .. is he mistaken??
