A scan of the server from an outside machine. The server needs SSH and the site outside. Which ports are extra here?

$ sudo ip netns exec lab-outside nmap -n 192.0.2.1
Not shown: 996 closed tcp ports (reset)
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
5432/tcp open  postgresql
8080/tcp open  http-proxy

5432 and 8080.
None are extra — closed on the other 996 ports means the server is protected.
22 and 80.
