Comment on Dynamic DNS vs Dedicated VPN IP

As long as whatever firewall rules you’re using is capable of resolving FQDNs then I don’t see an advantage of doing this. Maybe in the off chance that your IP changes, someone else gets the new IP and exploits it before the DDNS setup has a chance to update. I think that’s really unlikely.

Why do firewall rules need to resolve FQDNs?

To resolve whatever hostname you’ve setup for ddns

Sorry, but I still don’t understand, what’s the need for that?

Because you’re not going to setup any rules pointed to a dynamic public IP address. Otherwise you’re going to be finding a way to change the rule every time the ip changes.
The ddns automatically updates an A record with your public IP address any time it changes, so yeah the rules would use the fqdn for that A record.
