Don't modify /etc/rc.d/init.d/iptables
It could be changed by updates etc.
Active Monitor fools with the rules in that file also

Make a little script or add to end of /etc/rc.d/rc.local
#======================================================
#Load the NAT module
modprobe iptable_nat
# Turn on IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
# MASQUERADE the connection
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
#=====================================================

The above is a swag, it may get you startede.
