I need assistance configuring ISA 2000 on a Windows SBS 2003 to allow Mozypro online access. I contacted Mozy and they require access via port 443. I created what I believe to be a protocol rule for internet access for SSL but no luck. The only way I can get Mozy to work is to change authentication from Integrated to Basic. This allows Mozy to connect fine but then all the clients are prompted for user credentials every time they open a browser. I'm thinking I'm not setting up a rule properly. Any help would be appreciated.
