I thought the issue was only effecting my OWA site, which I have been unable to contact since upgrading, but it seems no web traffic is making it through.
Since upgrading all connection attempts to my OWA site (being served on https) have timed out. This was working fine prior to the switch over (all settings are identical to prev version). To test further I enabled http access to a test site (using a rule and server previously tested under last install) and those connections are timing out as well.
So far I have not seen anything in the IPS or Packet Filter live logs to indicate traffic is being stopped or dropped and both sites test fine internally. Has anyone else seen this?
I will sift through all logs and post any findings tomorrow.
