Hi, is there a simple way to do SNAT for packets that originate from the router itself? I want to set a static IP for a multihomed router that does forwarding, too. I've tried to set: iptables -t nat -I POSTROUTING -p tcp --dport 4711 -j SNAT --to-source 1.2.3.4 but that does SNAT on forwardes packets, too.. Do I miss a rule on "-t filter OUTPUT"? maybe mangle with -j MARK and SNAT packets that have a mark set? Christian
