over the past three days traffic from my remote servers stopped working. it too me a while to figure out what was not right..but finally after digging i found the automatic firewall rules for the wan interface got deleted after the upgrade. once i re-created the wan firewall rule for the port forwards traffic began flowing again. As a test i deleted the port forward rebooted the firewall and then recreated the port forwards...the traffic was blocked..after another reboot no forwarded traffic was allowed..i had to create the wan firewall rule to allow the port forward.
so with some more exprimentation...i deleted the port forwards and wan rules...lt the system sit for 5 minutes and then recreated the port forwards...a few minutes later the rules appeared in wan properly. IME BSD sometimes jsut get flaky in the firewall someteims(hit it a few times with pfsense too)...it seems to have settled down now...will keep an eye on it.
