- Get a box with two NICs
- Turn on one at a time (modprobe and ifconfig)
- Figure out which one it is (eth0 or eth1 and which card)
- LABEL it
- Make sure they have different IPs and netmasks
- If they have the same IP or netmask, they won't work
- If they're on the same subnet you'll confuse yourself
- Routes to each net and ONE default
- "echo 1 > /proc/sys/net/ipv4/ip_forward"
