6: VPN Configuration

• Split Tunnel

• VPN 1

• VPN 2 to VPN 5

The VPN tab that displays in ACEmanager is applicable across all

Sierra Wireless AirLink devices.

The AirLink device acts as a Virtual Private Network (VPN) device,

providing enterprise VPN access to any device connected to the

AirLink device even when a device has no VPN client capability on its

own. The AirLink device supports four types of VPN: IPsec, GRE,

SSL, and L2TP+IPsec. The AirLink device can support up to five

VPN tunnels at the same time.

IPsec

The IP protocol that drives the Internet is inherently insecure. Internet

Protocol Security (IPsec), which is a standards-based protocol,

secures communications of IP packets over public networks.

IPsec is a common network layer security control and is used to

create a virtual private network (VPN).

The advantages of using the IPsec feature includes:

• Data Protection: Data Content Confidentiality allows users to

protect their data from any unauthorized view, because the data

is encrypted (encryption algorithms are used).

• Access Control: Access Control implies a security service that

prevents unauthorized use of a Security Gateway, a network

behind a gateway or bandwidth on that network.

• Data Origin Authentication: Data Origin Authentication verifies

the actual sender, thus eliminating the possibility of forging the

actual sender’s identification by a third-party.

• Data Integrity: Data Integrity Authentication allows both ends of

the communication channel to confirm that the original data sent

has been received as transmitted, without being tampered with in

transit. This is achieved by using authentication algorithms and

their outputs.
