Can route through bypass firewall?

I have some services I want accessible at my server, but ALL services should be accessible only from one eth iface which will be IP'd inside the NAT. Then there will be two other interfaces (one hdlc, one eth) which are both IP'd outside the NAT which I want to perform as transparently as possible as a path straight through this machine ... since the NAT and general system firewall will be performed at another machine.... so I am trying to just hand all the packets between the HDLC and that other machine.

Is there a trivial way to do this - like with my routing tables? Or what are the key concepts I should be looking under to make this happen?

Thanks for any guidance.

Partial Answer

So the main thing here is I want that pass through to have zero access to anything on the server. I just want it an unrestricted point to point gateway.

So I think a partial answer to my own question is that I just need to make sure any/all services running on the server are set to listen ONLY to the IP or eth0 on the internal network. If that is fixed then I don't need to put any effort into closing ports on the two external interfaces.

Am I on the right track?
