We have just installed a new ASA5510 and I have a problem with I think Natting. Forgive me if its really simple but I have next to no experience of Cisco boxes.

I need to allow SMTP from an outside link. Its not the Internet.

The source IP is

The Firewall Interface is

The Inside Interface is

The SMTP server is

I need to NAT this link 'cos there are other smtp links that expect the 52.4 interface. The Packet Tracer within ASDM fails at the NAT stage and I notice that both Input and Output interfaces are both the 52.4 interface. Can anyone tell me what config I should have to NAT between the two boxes? I currently have a static one

Thanks, Ray
