Hi Raji, You can't auth at the firewall and at the Web site unless you use client certificate authentication at the firewall.

Works fine. If I enable authentication on the Web Publishing Rule to use a local group so I can control who can access OWA then I get a 'page cannot be displayed' error - '500 Internal Server Error - The network logon failed. (1790). Internet Security and Acceleration Server. This local group is made of users from a another forest/domain that is trusted by this organisation. If I allow any requests it works fine. Help!!
