I'm not using Port 22 for my SSH but something above 47000
I have ufw (uncomplicated firewall) installed and have unblocked "ssh" and "http"
When I look into the current ufw status he says that Port 22 and Port 80 are allowed from everywhere. I configures this thing via SSH
My SSH connection wasn't interrupted by it. Even tho I'm not using Port 22 for my SSH. Not I've unlocked that special port for 47000+ too. Now I have both ports open on as well IPv4 and IPv6
Do I need to have both unlocked? Can I delete the Port 22? I wouldn't ask this question if my SSH connection would have collapsed but now I'm confused what Port SSH really uses
Is the 47000+ Port only used for the handshake?
I'm sorry for this (near-to-irrelevant) question but I fear that I might never be able to SSH to my server again when I have a wrong Firewall config
