Hello, My server is on Mandriva 10.1 eth0 is WAN with static IP connected to 512K DSL eth1 is LAN - 192.168.0.0/24 and 192.168.21.0/24 I have used webmin and done : Do network address translation on external interface:eth0 This gives the following entries in iptables : # Generated by iptables-save v1.2.9 on Tue Apr 26 14:50:01 2005 *nat :OUTPUT ACCEPT [0:0] :PREROUTING ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -o eth0 -j MASQUERADE So should I just masq all out ? Is it possible to use my static IP or subnets details to rewrite the above masq rule while I am doing a NAT on eth0 ? If yes how ? Thanks Varun
