Hi everyone!

I’m looking into self-hosting, and I currently have dynamic DNS set up to point to my home IP.

My question: is it worth getting a dedicated IP through a VPN?

I’m pretty technically savvy, but when it comes to networking I lack practical experience. My thought is that pointing my domain to a dedicated IP and routing that traffic to my home IP would be safer - especially if I only allow traffic on certain ports from that IP. Just curious if that idea holds up in practice, or if it’s not worth the effort.

        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.

              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.

                    No fucking shit? In that scenario your friend could use DDNS and you point your access rule to his FQDN to allow access.

                    Did you really ask me a billion fucking “why” questions just to come back and fucking what prove me wrong? Is this a good use of your time? I literally thought you were a noobie looking to understand.

                    Fuck off.
