I've had issues with the windows firewall and linux MTU setting before, and
this kind of sounds similar to that. At home I have a linux firewall and it
does some fancy traffic shaping and such so I can 'promise' traffic and
latency for certain 'important' things like battlefield2. I also have a
gigbit switch that supports jumbo frames. The combination of jumbo frames,
the windows firewall and the linux firewall/traffic shaping, didn't do so
hot. If I wanted to have the windows firewall on I had to disable jumbo
frames on the switch, and lower my MTU on the linux box to 1400... Because
you are going through a router to your linux box, I would bet you are
experiencing something similar. try disabling the windows firewall...
