Here is an iptables config from my wifi-network:

My configuration is: LAN (192.168.2.0) -> (192.168.2.254) wifi-router
(192.168.1.18) -> (192.168.1.1) InetServer (PPPoE connection) -> DSL
modem -> Provider
Router is taking IP address via DHCP from InetServer, and InetServer is
taking DNS and etc from provider.
Sincerely,
wanderlust
