#ipfw — Public Fediverse posts

#FreeBSD #HotTake: Even though everyone with deeper #firewall juju than myself says #pf is better than #ipfw, so I guess it must be, I still like knowing my rules by numbers that don’t change. Plus I have tools written over many years around ipfw and would need to totally redesign them conceptually for pf. I don't have enough working years to do that.

#TIL: #ipfw’s “me” does not include the local network's broadcast address.

I know this because I’m building the bespoke packet filter for a new system (to characterize+quiet its real background noise) and had a long WTF session because I missed the last octet.

Has anyone gotten sslh transparent mode working on #FreeBSD with #pf instead of #ipfw ?
