DNAT / SNAT Problems

zwiback
I got a Zyxel ADSL Router, that's configured as a Bridge.
I got three Network Interfaces (RED PPPoE, Green 172.23.40.1, and a DMZ 172.24.40.1).
But first I just setup the PPPoE and the green interface.
After that I configure the SNAT/DNAT Rules like this:

Out Internal_Network__ -> Any / Any Red_Interface__ None
In Any -> Red_Interface__ / Any None Internal_Network__

As soon I save the In rule the firewall doesn’t answer any Pings and I cant connect to the Web GUI.


Please Help me.

    Also, something else I just noticed is that your DNAT is set to route all of your internal network.  Try routing internal_interface to Red_interface.  I make that same mistake when I start doing things really quick and don't think about it.
