Hai, I have installed the IPMASQ package, and now I can ping myself. I now that this has something to do with the firewall rules, but I can find any documentation on how to use the IPMASQ package. I did do a man ipmasq, and looked in the /use/doc/ipmasq directory but I can't find any good example. My setup is very seimple, just mu network on eth0 (192.168.1.x) and a ISDN router on eth1 (192.168.2.x). Hope you can help me with this Ries van Twisk
