IMO Linux is significantly better than the *BSDs at this particular use case.

But don’t have to cobble together a bunch of arcane iptables commands and then combine bpf and other userland tools … when one can just use the clean syntax of PF especially for home use that’s a clear win.

I've used both extensively and I find eBPF+iptables (and sometimes nft) significantly more flexible and easier to use in the real world (not just simple examples) than PF. shrug

If you did manage to figure out the iptables commands you now have to change them over to nftables. :)

Not having to manage two rulesets -- one for IPv4 and one for IPv6 -- is pretty well a killer feature in my mind.

Linux certainly offers much better functionality overall but the tooling for this is a poorly documented and inconsistent nightmare.

There is definite lack of a declarative tool that glues it all.

Typical hardware switches and routers just have one (sometimes expanded by includes/macros but still) config syntax to control every part of networking stack.

So you can configure interface and set its vlans all in one place instead of creating a dozen of ethX.Y devices then crerating a bunch of brY bridges and then attaching the interfaces to them

In linux instead you'd be using iproute2 set of tools to configure interfaces and static routing, iptables for IP ACLs, ebtables for ethernet ACLs (or now nftables I guess), without any tool to apply/revert changes at once

Many tried doing that but IMO haven't seen anything good.

Many also try to "simplify" iptables and all it ends up is me being annoyed coz I know which iptables commands I need to run but I need to translate it back into "higher" level config syntax. One exception being ferm ( http://ferm.foo-projects.org/ ), because it keeps iptables-like keywords just expands on that, but it is iptables only and kinda superseded by nftables syntax anyway.

I would trade firewalld for pf in an instant.
