AnyConnect VPN fails on Mac with MobileMe Back to my Mac enabled

Cisco ASA AnyConnect VPN fails to connect. User sees two connections, and then a error box.

AnyConnect VPN fails on Mac with MobileMe Back to my Mac enabled
Symptom:

VPN connectivity failure on Mac when MobileMe "Back to my Mac" is enabled.

Conditions:

Problem occurs for MobileMe users with "Back to my Mac" enabled. Both MobileMe "Back to my Mac" and Cisco AnyConnect insist on using a virtual adapter with the same name "utun0". Neither application is capable of creating a secondary interface for example "utun1". Since MobileMe initiates when the computer boots, it always grabs the utun0 interface first, causing Cisco AnyConnect to fail.

Workaround:

In order to use AnyConnect for the purposes of the pilot, you must turn off Back to my Mac before you connect to the VPN. Once VPN is disconnected, you may re-enable Back to my Mac.

Cisco Bug: CSCTq62860

First found in Anyconnect client version: 3.0(629)
