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.

NeutronBoy • Feb 24, 2015 • View on HN

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.
