Port Forwarding on Cisco PIX 525

Posted on 2005-05-02
Last Modified: 2013-11-16
We recently aquired a Cisco PIX 525.  I need to forward terminal service (3389) requests to a local machine.

The local machine is with it's gateway set at (internal ip of the PIX)

I can't seem to get the correct set of access-list and static statements together to get this to work.

Any suggestions/comments on this config? I'm open for all improvements but I mainly need 3389 working.

I am not limited to only doing forwarding.  We have also been given a few additional IP's and NAT(ing) one of them to this machine would be great, and again I don't know how to do it.

the lines I've used in an attempt to get this done are:
>access-list inbound_traffic permit tcp any interface outside eq 3389 log
>global (outside) 1 interface
>nat (inside) 1 0 0
>static (inside,outside) tcp interface 3389 3389 netmask 0 0
>access-group inbound_traffic in interface outside
>route outside 1

    Accepted Solution

    Here you go try this:

    static (inside,outside) tcp 3389 3389 netmask 0 0
