I'm troubleshooting an Outlook Anywhere issue with a new Exchange 2010 server. The server in question, MS2010, is behind a SonicWALL NSA 2400 device and works wonderfully except for Outlook Anywhere. Outlook Anywhere works internally and I've verified (through Ctrl-Right Click --> Connection Status) that I'm able to connect to MS2010 over HTTPS.
When trying to connect to the server using HTTPS from outside the firewall, I'm unable to do so. A Wireshark trace shows 30 or so successful HTTPS packet transmissions, and then it fails with 3 straight transmissions to a destination port of 135. I have no idea why my computer is attempting to access anything on port 135 since I've setup my profile to use HTTPS on both slow and fast connections.
I'm 99% certain that the firewall is configured correctly. I run Outlook Web Access (also HTTPS) on the same server and there are no issues with access.
EDIT: My Autodiscover settings are correct (as far as I can tell). My server passes the Outlook Anywhere and Autodiscover tests at https://www.testexchangeconnectivity.com/.
I've been using the RPCPing utility to troubleshoot and have come across the following results:
Internally-

What should I be checking in order to troubleshoot my Outlook Anywhere issues? I'm using Windows 7 SP1 for internal and external access.
