hi,

i have created a knoppix machine with two network cards to act as simple router and let packets pass through the knoppix router between subnets
it might be a simple command via ip command but my linux skills are poor
please advice
thanks

You've not given us much information about your subnets and IP address configuration, so I am going to assume that you understand enough about TCP/IP to set all this up correctly, and your only remaining problem is how to get Linux/Knoppix to actually start forwarding packets.

The low level answer is to
echo 1 >/proc/sys/net/ipv4/ip_forward

This is usually enabled in the boot scripts by setting the appropriate entry in the file /etc/network/options [Hint: ip_forward=yes].

Disclaimers:
I am also assuming you have a hard disk install.
This works with the 2.4 kernel, I'm not completely sure about the 2.6 kernel.
