Split Tunnel

The AirLink device supports Global settings with one encrypted tunnel and one
open tunnel. A sample server subnet for a Global setting would be 172.16.1.0/24.
Global settings VPNs should be set up with care, as a Global settings
configuration with both an enterprise VPN and access to the public Internet can
inadvertently expose company resources.
