Hi, I am a newbie and I was reading the howto for packet filter. The howto has the following picture: Incoming / \ Outgoing -->[Routing ]--->|FORWARD|-------> [Decision] \_____/ ^ | | v ____ ___ / \ / \ |OUTPUT| |INPUT| \____/ \___/ ^ | | ----> Local Process ---- The input filtering is done only for local bound packets and after the routing decision. Is the above true ? Is there a facility to perform input filtering before the routing decision ? Thanks. Bhasker. __________________________________________________ Do You Yahoo!? Tired of spam?
