Migrate 3CX server with a new firewall with new public IP

[kanewong]

Hello;
I am working on migrating/moving the current 3CX server (Linux) with a new firewall, in which a new public ip address will be used.
With my initial test, I change the gateway ip address on 3CX server with the new firewall and completing the firewall checker test, it is all good.
Except I have to update my public DNS server for the new public IP address, what else I have to change as well? And do I need to register all my 3CX mobile app on cellular phone?

Thanks in advance.

If you're using 3CX's FQDN then this will update automatically. Apps point to the FQDN so as long as the DNS servers where the apps are update often enough there should be no issue. Be sure to give your SIP provider your new IP and turn off admin console restrictions before moving so you dont get locked out.
