simple PAT question
If I have a host on an internal network listening on a port such as 25 SMTP, on the ASA can I translate a different port such as 225 to 25 while at the same time allowing port 25 to the host to pass through unchanged and actually receive the return traffic for the external hosts connecting on port 25?
It seems to me like the problem is with the return traffic from the server which is always translated to 225 when I enter a rule such as the following.
static (inside,outside) tcp 10.0.1.43 225 10.0.1.43 smtp netmask 255.255.255.255
If anyone can advise I'd appreciate it.
