Could  there have been existing connections when you made the change and the firewall didn't see the SYN of those, so it's blocking them?

Just as the previous poster said, if you had existing connections and then changed the rules, they won't apply immediately to existing or established connections....

If you need it to apply immediately, reboot the firewall.
