I have an old laptop i'll be running knoppix
I will be using it as a firewall. - iptables.
It only has one ethernet port, i'll be wanting more. The firewall i'd run in it would control the communication between the connected computers.
What USB multiple ethernet port adaptors, would work with knoppix?
