M2M Cellular Gateway
5.5.7 L2TP
Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks
(VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or
confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to
provide privacy. This Gateway can behave as a L2TP server and a L2TP client both at the same time.
Deploy a security gateway for local office and establish a virtual private network with the remote
gateway of another office by using L2TP tunneling. So, all client hosts behind local security gateway can
make data communication with others behind remote gateway.
Or when you are a mobile user with your notebook or carrying along a security gateway and you
want to access the servers and database in company headquarters (HQ). Moreover, the security
gateway in HQ supports the L2TP VPN server function. So you can dial in the HQ gateway and access
the HQ resources by establishing an L2TP VPN tunnel. It is a virtual private network between your
device and HQ gateway for your resource accessing.
In "L2TP" page, there is the "Configuration" window to enable the L2TP VPN function. The security
gateway can either take a "L2TP Server" role or "L2TP Client" role or they both. Define and choose
either one role for your router in the "Configuration" window and configure all required parameters
Index skipping is used to reserve slots for new function insertion, when required.
