Wireless Access

This problem occurs only on the iPhone.

On Android and Windows 7 , VIA client working stable.

The problem is that after a successful connection, i put VIA in background and usin web browser, voip.

Within 1-5 minutes vpn connection is lost.

Has anyone encountered a similar problem?

Did you get this resolved?  We had the same issue with one of our customers using VIA.  The problem was related to the policy tied to the via user role.  The via client requires communication with the controller, if this communication is not allowed between the client and the controllers internal IP address, then the client disconnects after 1 minute.  Allowing this communication in the user role that is assigned to the via client solved the issue for us.

I solved the problem.

Internal ip address, that i use in VIA profile was not maped to any vlan on controller.

Changing VIA profile ip to vlan ip and it fix iOS session connection drop problem.

It was my stupid mistake, but it's strange that the problem affects only on iOS.
