🇧🇷🇴🇳🇿🇪🇦🇬🇪🇭🇴🇬🇨🇷🇦🇳🇰🇪🇷 (npub1dsx…nhxs) Alex Gleason (npub108p…yev6) Outbound firewall would operate on the destination port. Simply allow 80/443 for only web for example.
But for the connection to work the inbound firewall has to allow packets to the random port. That's why the firewall has to be stateful, inspecting the TCP packets and keeping track of connections so it knows that packets to random port number are for a connection initated from inside to an allowed port.
