Franco, I will continue to close bugs which have not been demonstrated on
freebsd. I will not continue this argument.

Yeah, that’s what I expected. It’s pretty trivial to fix, and I’ll land it
along with the other fixes in the review above.

The TCP and UDP hdr th_sport = uh_sport = 61525 and th_dport = uh_dport = 47873
looks correct.
ip_src = {s_addr = 0}, ip_dst = {s_addr = 0}.
And this one is a TCP connection proto = 6 '\006'

Can you print pd->sport and pd->dport, because I suspect those are the issue,
not src or dst.

That pf_syncookie_check() is in a if statement which doesn't matter if we
enabled the feature or not.

I copied the configurations from OPNsense, so some of them may not exists in
base FreeBSD, and it shouldn't affect anything.

--- Comment #7 from Kristof Provost ---
How are you getting a syncookie panic if 'set syncookies` is not part of the
ruleset?
Also, what is net.pf.share_forward? I can't seem to find that in the code.
Does this happen on 14?

I haven't had a chance to test it on base FreeBSD yet, which would require me
