PF Syntax

[openbsd_]

Sirs. I'm coming from OpenBSD and I wonder whether the syntax for PF is the same on FreeBSD? Thank you, all.

Not exactly. FreeBSD's PF got imported from a relatively old OpenBSD version (4.5 if I remember correctly). OpenBSD's PF and FreeBSD's PF have diverged quite a bit over the years.

Is there a FreeBSD syntax for allowing:
- inbound traffic to specific ports
- blocking all traffic.
- "passing all outbound traffic".
Would you please be so kind and refer me to the right tutorial/source?

Thank you, sir.
Essentially I would do:

block all
pass out
pass in proto tcp from any to any port 22
