Another thing you can try is throwing a bunch of master server values in your server.cfg:
seta sv_master1 "masterjk3.ravensoft.com"
seta sv_master2 "masterjk3.ravensoft.com"
seta sv_master3 "63.146.124.53"
seta sv_master4 "204.97.248.90"
seta sv_master5 "clanservers.net"
seta sv_master6 "master0.gamespy.com"
BTW, don't know about you guys but since I rarely yews X-fire I tend to check the trackers on this site to see if dudes are playing. For this new box I've been using the JA+ one until Guard gets an official one up.
