#Allow all connections OUT and only existing and related ones IN"
iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j
ACCEPT
iptables -A FORWARD -i eth1 -o eth1 -j ACCEPT
# Enable SNAT (MASQUERADE) functionality on eth0"
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
in this scenario eth0 is external and eth1 is internal

Subject: Setup simple PC-based router using IPTABLES
> Hi,
>
> I need some help on using IPTABLES to setup a simple PC-based router (for
> LAN usage).
> The PC consists of a 10/100 NIC on eth0, and a gigabit fiber NIC on eth1.
> The gigabit fiber NIC is connected to another fiber-based port, whereas
> the 10/100 NIC is connected to a 10/100 hub. Now, for all packets coming
> from eth0, forward it to eth1, and vice versa.
> Could anyone verify/suggest commands to set for this setting?
> # iptables -A FORWARD -i eth0 -o eth1
> # iptables -A FORWARD -i eth1 -o eth0

> Is it that's all we need to do? Thanks.
