perhaps (most probably) you should change your mtu settings of your eth0

I guess it is already. I'm almost sure I saw that value in the output of tcpdump. The MTU for ppp is 1500, instead, and I think that's right: 1492+8, the eth0 MTU plus the 8 byte overhead of ppp.

But I need to check again. On Monday I'll be back with some logs and
outputs...

Best regards.



This is the output of
/sbin/ifconfig.... My MTU is 1500 on both ethernet cards and 1492 on ppp.I have no problem with net surfing.Please check!!!
