VPN Dropping - NAM 4.10 anyconnect

[JonathanC1]

Hi Folks,

Using 4.10.x new version anyconnect hitting a problem where I go to establish to VPN then shortly afterward (5-10 seconds) the VPN fails "The network interface for the VPN connection has gone down."

NAM module is causing the problem (note: when it is disabled no issue) - the NAM starts to try to connect to a wireless/corporate network when we connect to VPN 5-10 seconds in which bombs out the VPN connection (that is where we get the error for network interface has gone down in DART log.) Any ideas of how this could start happening only changed AC version?

The first thing I would check is to make sure the NAM filter driver is NOT bound to the AnyConnect Virtual Adapter.  If it is uncheck the box in the image below from the "Cisco AnyConnect Secure Mobility Client" adapter.

If this is the issue you are hitting it is being tracked under https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvw50627/?rfs=iqvred and will be fixed in a future release.
