The entry for sysctl was correct as posted by someone else before.  Other than
that, you just need iptables rules for the forwarding.  Something like:

iptables -I FORWARD 1 -i eth0 -o eth1 -j ACCEPT
iptables -I FORWARD 2 -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j \
ACCEPT

Although in your situation you might trust the external interface more than
that.
