What is your modem?? please note that my eth0 is the interface to the
LAN and eth1 is to Internet.
I didn't change nothing, I fixed only IP numbers for my comfort
(especially to the internal interface, as it is a router/proxy/gateway).
I get the DNS numbers from modem.....and I didn't touch any MTU setting
(Linux is not Windows..in a network!!!): it works just out of the box!!
Any way please post again the output of command route -n and revert to
the original MTU values....
