YEs, the firewall has the ports 6699 and 6257 open and forwarded, that should be both UDP and TCP types. Its a Linksys switch with internal software firewall on a cable modem connection.
I am on primary connection to Win MX.
I alos seem to have bandwidth issues with my ISP too, if that makes any difference.
One minute I get as low as 33kbps then later I can get up to 2.2 Mbps so I dont know if its my stuff or ComCast crap. All this used to work perfectly under Road Runner ISP a month ago, with no changes.
I am running mx monitor 128Eb and WinMX 3.54 beta 4, if that makes any difference.
I seemed to get some search results in the first 1 minute after network connection but then nothing.
