I am having a problem with RPC over HTTP (Outllook Anywhere). Last night, I switched from using a Netopia Router to an SSG-5 Firewall (Juniper). Until the switch over, Outlook Anywhere was working great. Called Juniper and their techs spent the biggest part of the day on the phone--and remoting in to the firewall to check the firewall and the configuration looks correct for the simple setup I have. They think that the Barracuda Spam Model 300 firewall is blocking the RPC over HTTP. I am not to sure if they are correct. Has any of you experts had a similiar problem? I have made sure the HTTP and HTTPS ports are open. Inside of my network, I can use outlook /rpcdiag-and it connects perfectly to Microsoft Exchange 2007 server with no problems. Any thoughts are help is appreciated. Juniper can't figure it out and Barracuda Techs give me the old upgrade the firmware bit--which I did--but it didn't slove the problem.
