Solution already mentioned before:
There seems to be alot of this going on lately. The consensus seems to be that ipv6 is causing it. If you want to disable ipv6 you just add the following line to either /etc/modules.conf for 2.4 kernel or /etc/modprobe.conf for 2.6 kernel.
alias net-pf-10 off
However I discovered that the main reason for slow internet traffic was a problem on the LAN.
LAN is behind IPcop. Green and Orange network were connected to 1 switch.
This caused a lot of "martian source" messages by IPcop.
Using a separate swithc for Green and Orange network solved all network congestion problems.
