After connecting to a corporate lan using a 3rd-party VPN client, the WSS agent turns off and on. Both VPN client compete, resulting in tunnel flapping.
The WSS Agent is designed to operate in a split tunnel environment. Essentially, both VPN clients are competing to establish tunnels, which might create a condition where one client is trying to establish a tunnel within a tunnel.
For both clients to function, configure as Split-Tunnel VPN connections.
