Comment on Dynamic DNS vs Dedicated VPN IP
VelociCatTurd@lemmy.world 8 months agoBecause 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.

What’s the need of the public IP in the firewall rules?

If OP needs a firewall rule to do any number of things that a firewall does.

I’m curious to know in which case is useful to know the public IP in a firewall rule because I’ve never used it.

An access rule for instance. To say to allow all traffic or specific types of traffic from a public IP address. This could be if you wanted to allow access to some media server from your friends house or something.
