Mox behind Nat dynamic public IP

[jujoparo]

Dear sir.

I have a homelab sever behind a dynamic public IP router with NAT. I have also a daemon that continuously updates the IP in the DNS server.

Talking about Mox, Is It possible to use a public dynamic IP behind Nat? Is it possible to specify a Fqdn in the IPs settings like this:

IPs: mailserver.domain.com, 192.168.1.1
NATIPs: 192.168.1.1

What would it happen if after the server starts the pubic IP changes? Would it be necessary to restart the mail sever?

Thank you very much for your help.

It should be possible to run mox in such a setup, thought it's indeed not a great situation.

You would normally configure NATIPs with your actual external IPs. You could try to automated setting them. But you can also leave them empty. The DNS selfchecks will complain, but you are of course free to ignore those warnings.

You wouldn't have to restart mox when an IP changes, at least not if you don't change mox.conf (which has the NATIPs setting). If you do change NATIPs, then you must restart mox afterwards.

Hope this helps.
