Save your money and just buy Hades, it’s fantastic.
Literally unusable.
I would’ve if I was wrong
If you really think someone is wrong don’t ask them “why, why, why” incessantly like a toddler, grow a pair of balls and just speak your mind.
And in this case I meant “your IP” as in, the grand scheme of things “an IP address that you own”, a VPS for instance, not necessarily the destination. Obviously you wouldn’t need to tell a firewall what its own public IP is. Have I clarified my thought to your standards?
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.
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.
If OP needs a firewall rule to do any number of things that a firewall does.
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.
To resolve whatever hostname you’ve setup for ddns
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 old IP and exploits it before the DDNS setup has a chance to update. I think that’s really unlikely.
Edit: just to add to this, I do think static IPs are preferable to DDNS, just because it’s easier, but they also typically cost money.
