Topic: Portforwarding with one NIC

[Olivier]

Hello togheter

I have one SME 5.6U4 in a DMZ behind a firewall. This server is in server only mode. On this SME I have installed portopening and portforwarding (from http://mirror.contribs.org/smeserver/contribs/dmay/mitel/contrib).

Now I would like to forward specific traffic to an other server in the LAN behind the firewall.
 
I have opened a port, for example 8080.
I have set up a portforwarding rule for example from 8080 to an IP-adress (private range) to port 80 in the LAN.
All neded ports on the firewall are opened.

Should this work with only one NIC and in server only mode?
What have I to do?

Thanks for any hints?

Olivier

Hallo!
I dont believe it will work. to be in "router" mode ie. gateway the server needs 2 nics (or 1 modem, isdn card) etc.

It is also not of very much use!!! Why send all portwarded traffic to another ip address?

I take it that the firewall is also the standard gateway of the network? Then you can portward all traffic to the right ip:port here!
Your clients will be able to see a server in the orange network anyway.

You are suggesting a breach of security in that you want to forward  packets into the otherwise protected Lan.
