Configuring VPN Termination
Use the Setup Advanced Settings - VPN Termination page to configure VPN
protocols and manage VPN tunnels. A VPN is a connection between two endpoints
in different networks that allows private data to be sent securely and transparently
over public networks or other private networks. With a VPN, you can send data
securely between these two locations or networks. This is accomplished by creating a
"VPN tunnel." A VPN tunnel connects the two PCs or networks and allows data to
be transmitted over the Internet as if it were still within those networks. The VPN
tunnel uses IPsec (Internet Protocol security) to encrypt the data sent between the
two networks and encapsulate the data within a normal Ethernet/IP frame so as to
transport the private network securely and seamlessly through other public or
private networks.
A VPN provides a cost-effective and more secure alternative to using a private,
dedicated, leased line for a private network. Using industry standard encryption and
authentication techniques, an Internet Protocol Security (IPsec) VPN creates a secure
connection that operates as if you were directly connected to your local network.
For example, a VPN allows users to sit at home and connect to his/her employer's
corporate network and receive an IP address in their private network just as though
they were sitting in their office connected to their corporate LAN.
Another advantage of a VPN network is that it all proprietary Microsoft Windows-
based networking protocols can pass through the router using the VPN tunnel to
access corporate shared network drives.
Note: If you are not familiar with the advanced settings detailed in this section,
contact your service provider before you attempt to change any of the wireless home
gateway defaults advanced VPN Termination settings.
Click VPN Termination in the Advanced Settings section of the Setup page to access
the Setup Advanced Settings - VPN Termination - Status page. The VPN
Termination - Status page allows you to create, configure, and control IPsec VPN
tunnels.
