Firewall Usage Debate
Comments debate the sufficiency and use of firewalls (built-in OS ones like iptables/ufw or external like pfSense) for network security control, often arguing they already provide needed features instead of new OS capabilities.

Seems like an edge case. 99% will be happy with the OS firewall.
You can get better firewall control than just open/shut
There are firewalls with those features.
There is a firewall right? it is just off by default.
Your observation doesn't contradict the use of firewall rules to accomplish this.
IP-based firewalling, if available, perhaps.
Are local firewalls not cool anymore or something?
Turns out you've been running without a firewall this whole time! Time to get a firewall. PfSense and Opnsense are good options.
"use a firewall" -> "use an external firewall". :)
Sounds kinda like a firewall would server you better. Not that I don't think you should or shouldn't be able to have this feature.
