I'm having a heck of a time setting up these fiters. I seem to have most of
them working but I am unable to access OWA from outside the office. As soon
as I unload IPFLT things are good. From what I understand it just uses port
80 (unsecure) and 443 (secure). No mater how I try I can't access with
filters up. I am able to browse and with that comes the assumption that
port 80 is open. Is there anyone that can shed some light on this subject??
