I need to do it one by one, because I want it to be dynamic. I mean: I want to be able to change external ip for a specific server at any time. I am building a set of scripts where an internal server will request from the router to change his external ip. The router will change and reload his configuration dynamically. I have a set of 10 public ip addresses for about 5 internal servers. My router is a Linux Fedora 11 box, kernel 2.6.30.10-105.fc11.x86_64 with iptables-1.4.3.1-1.fc11.x86_64 installed. Is there somewhere a step by step howto to help me configure iptables? Maybe a thread in this list? I checked some threads but I found only configurations for range of ips, not for individual ips. I checked some iptables Howtos: There are a lot about one public ip to multiple internal, I haven't found any on multiple to multiple. Thanks for help Patrick
