Re: Policy NAT Configuration

I may not totally understand what you are trying to do but I think you need to do something like this.

access-list nat2_acl extended permit ip host 10.3.25.2 X.X.X.X 255.255.X.X

^^^Where the X's are the IP address range cust B is using (policy NAT based on destination)

nat (inside) 2 access-list nat2_acl

global (outside) 2 192.168.56.2

Please rate if this helps. Thanks
