Port translation on one DMZ server via Sonicwall

By erikbalek ·
We have a Sonicwall TZ170 Enhanced firewall with SonicOS Enhanced
We have a mail server that we changed the SMTP port from 25 to 587, since many ISPs block port 25. This causes it to not recieve mails, since they are all sent on the standard port. I want to do a port translation for that server, but when I try to add it to a new NAT Policy, I cannot select it in the dropdown list, only DMZ Interface IP and DMZ Subnets are in the list for Destination. The list is only different Address Groups, but not those defined for DMZ. No Address Objects.
Is it not possible to do this, a translation of the port to the same IP? Is it only for LAN?
Also, when I select Original/Translated Service, those lists are also empty.
Is there anyone with similar gear and needs that have tried this?

Port translation on one DMZ server via Sonicwa

It is possible to have a PAT on DMZ . I hope u tried the basic trying the interface in a different browser. Sonicwall 3.1 some times have browser issues. Also please check if the address objects are created properly and listed under Network Address Object .

Rest should be the same as you a create a normal PAT .
