NAT Rules ASA 5510 8.3
I am using the ASA 5510 version 8.3 and I am trying to set up a NAT rules, but I am not a expert with ASA....so I will post my doubt here.
My customer wants to map the external ip address (eg: 22.214.171.124) to an internal mail server ip address (eg: 172.16.1.1).
Just to get email into the mailserver from outside.
I have created the object group to match the mail server and created access-list to allow just the smtp traffic, but i dont know how to set up the nat configurations.
Can you help me ?
My configurations untill now:
object network Mailserver
access-list OUTSIDEMAILSERVER-IN extended permit tcp any object
Mailserver eq smtp
access-list OUTSIDEMAILSERVER-IN extended permit tcp any
eq smtp object Mailserver
Apply the acl on outside interface
access-group OUTSIDEMAILSERVER-IN in interface outside
Now, I guess that I need a nat configuration, but i dont know how to set up and the better way to set up it.
