No double NAT (LAN->WAN->DMZ)

Unanswered Question
Jun 24th, 2008

Hi!

We have got the following Issue:

NAT from LAN to (external) Public WAN-Addresses is working fine.

NAT from LAN to (internal) Router Hosted Public DMZ WAN-Addresses (NAT LAN-Interface -> WAN-Interface -> DMZ-Interface) is not working!

The Router performs no NAT, obviously because of the public IP is hosted from the router themselve, so the Router tries to route the packets direktly without any NAT from LAN->DMZ.

Are there any workarounds (perhaps to trigger LAN-Hosts to performed NAT in any case?

Thanks!

I have this problem too.
