PIX Firewall "policy NAT" problem

Posted on 2006-05-30

Last Modified: 2013-11-16
I have a PIX 501E that I'm using VPN to connect to several locations via static tunnel and VPN client.  Everything works and there's no problem.  However when I use the PDM I get the annoying message :

PDM has encountered a firewall configuration command statement that PDM does not support.  Configuration parsing has been stopped. BLAH BLAH BLAH..

PDM does not support "policy NAT" commands in your configuration.
(We've seen this before)..  

Here is the offending line in my case:  
static (inside,outside) access-list trans 0 0

I'm not that great with command line or IOS, so I prefer to use the GUI.  How can I alter my configuration to accomplish the same objective w/o having to use "policy NAT" in my config?



Here is my config:

Note: the one VPN tunnel that goes from 192.168.2.X (our side) to 68.241.41.X has to have the 192.168.2.X get natted to 10.254.218.X before getting to because of a duplicate IP subnet on the 68 side...

There's no PIX501E so I am assuming that it is a typo on your part. Its either PIX501 or PIX506e

Unfortunately there's no other way to modify your configuration other than to change your internal IP scheme. I know it is easier said than done, but there's no other means.

Policy NAT is an advanced configuration and the PDM does not support it. The ASDM I believe does but it is not available in the platform that you have.
