I am looking for a bit of help.
I need to enable NAT thought to a mail server for a couple of weeks while we carry out upgrades. Up untill now I have only used this Astaro as an http proxy.
As I don't have the option to enable the mail proxy features I was wondering if someone could point me in the right direction.
I have added an additional IP address to the WAN to be used for the nat.
I assume I would create an SNAT from the mail server OUTBOUND to the internet.?
Would I also create a DNAT inbound to the mail server?
In addition to smtp I need 80 and 443 open for webmail and 1 additional port for another service.
I have already configured the additional services and the host for the mail server.
Do I need to do packet filters in addition to the nat's?
An example would be of great use if anyone has one.
