8: Configuring AirLink Helix
• VPN VPN
The Helix Box can act as a Virtual Private Network (VPN) client,
providing enterprise VPN access to any device connected to the
Helix RT even when a device has no VPN client capability on its own.
The Helix supports up to two tunneling protocols, IPsec and GRE.
Both can be used at the same time if configured properly.
The Helix also supports split tunnels with one encrypted tunnel and
one open tunnel. A sample server subnet for a split tunnel would be
172.16.1.0/24. Split tunnel VPNs should be setup with care, as a split
tunnel configuration with both an enterprise VPN and access to the
public Internet can inadvertently expose company resources.
This section should give you a general overview of the VPN
capabilities. If you would like specific solution support, refer to the
recommendations and instructions provided with your VPN server
solution.
