Google tells me that port 760 has something to do with Kerberos registration. Apparently I don't know how to do "that" because this: # iptables -A INPUT -p tcp --sport 760 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT 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.
