Port Forwarding Without NAT

L0 Member

So, I have a very interesting network.  I have a media server that is on a separate VLAN.  There is no way for me to statically configure the client(s) with a static IP (they just search for the server).  It uses tcp/32400.  Basically, my host will show as coming from a different zone than where my media server is.  So, I need to forward any tcp/32400 requests from one zone and forward it to another.  For some reason, I keep hitting a wall when creating that (especially considering this is just straight L3 traffic - no NAT involved).  Any thoughts?


I should note that topology wise:

Internet --- ASA --- L3 Point to Point --- PA

The client is hanging off the ASA and as I said, it's just straight L3 traffic.  But, from the PA's standpoint, it would appear as coming from "Untrusted" to "Trusted" - just not with any NATing involved.

Have you tried Policy based forwarding Rule for this traffic? Configure it such as all tcp/32400 traffic sourcing from Untrust to forward on the media server's interface.

Let me know if that helps.
