Perhaps the windows box receives the ping and doesn't know how to route it
back. 'netstat -rn' will show you routes.  'ipconfig' will show

The linux box is probably OK - it receives & returns pings on the right
interace.  Check its routing though, do the pings really go out??
Easy troubleshooting - look at the 'activity' lights on your ethernet
switch or on the NIC's in the boxes.

There was another suggestion that there could a windows firewall.  Yep -
that's a very good suggestion.  Check the lights :-)
