I thought maybe you could try lowering the mtu size on the Linux box. I
had problems when I switched DSL providers and I had to manually switch
mtu size on my Linux box.

$ ping -c 10 www.yahoo.com
$ ifconfig eth0 mtu 1492
$ ping -c 10 www.yahoo.com
$ ifconfig eth0 mtu 1454
$ ping -c 10 www.yahoo.com
$ ifconfig eth0 mtu 1280
$ ping -c 10 www.yahoo.com

Not all sites ping back but Yahoo does but better to test with a problem
website as long as you know pings to the site work on the Mac or Windows
box.

I had my .bashrc set the mtu size on login.
