Could anyone verify/suggest commands to set for this setting? You don't need to use iptables at all if you just want a router. And perhaps you want to set up a bridge, anyway. > # iptables -A FORWARD -i eth0 -o eth1 > # iptables -A FORWARD -i eth1 -o eth0 > > Is it that's all we need to do? Those commands don't do anything useful. I suggest you start here: http://www.faqs.org/docs/iptables/ Google will also find you many, many descriptive articles on setting up routers and firewalls using netfilter/iptables. --- Charlie
