This is rather a network question, but it's really basic stuff, so I'm posting it up here.
I am using ufw as my firewall. Until recently I've only used GUFW to edit rules, but today I tried some manual config and it worked perfectly. And it was really cool. Actually, I realised that ufw was active and rules were applied without having to start GUFW. Nice!
But I've got a question.
What is the difference between these two statements:
192.168.1.1 465 ALLOW 192.168.1.50
192.168.1.1 443 ALLOW OUT 192.168.1.50
I am not talking about the ports, but the "OUT" statement (.50 is my machine, and .1 is the router).
Both rules allow connections from my machine to the gateway and then out to WAN. Everything works fine. But what does that "OUT" mean, how is it different from simple "ALLOW"?
