Apparently I don't know how to do "that" because this:

  # iptables -A INPUT -p tcp --sport 760 -m conntrack --ctstate

still doesn't allow the traffic through (not that I would want to
allow an --sport rule anyway but I'd just like to confirm that this
traffic is indeed responsible). What am I doing wrong here? I've also
tried simpler rules without conntrack or cstate but it's still not
getting through.

Incidentally I added kerberos and kadmin firewalld services without
effect either.
