The firewall is blocking access to a handful (correction) all of my websites and I have no idea why. I have changed nothing. Could this have come from a CWP7 update?
check TCP_IN, TCP6_IN, TCP_OUT and TCP6_OUT to make sure the ports are open. then restart csf.
Yes, I did that. Oddly enough after restarting the server three times it magically started working as expected. Thanks for the advice.
