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 172.24.52.50
The Firewall Interface is 172.24.52.4
The Inside Interface is 220.127.116.11
The SMTP server is 18.104.22.168

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
