VPN (Virtual Private Network)
Virtual Private Networks (VPNs) provide protected connections across the Internet.
Some companies and other organizations provide remote access to their internal
networks via a VPN. Employees are typically provided with software that makes
the VPN connection from a computer.
When a computer provisioned for this type of VPN connection is connected behind
the MG7540, the MG7540 must pass through the VPN traffic. The MG7540 is
configured by default for VPN pass-through. (The IPsec and PPTP Pass-through
settings on the AdvancedOptions page respectively enable IPsec and PPTP VPN
pass-through. IPsec and PPTP are protocols used in different VPN
implementations. The pass-through settings for both are enabled by default).
The most common type of VPN connection that MG7540 users will encounter is
the type of VPN described above, that simply needs to pass through the MG7540.
The VPN pages support features that allow you to terminate VPN connections on
the MG7540 itself.
The MG7540 can terminate PPTP, L2TP and IPsec connections in specific
scenarios. It can act as a VPN server to terminate PPTP and L2TP connections, for
example from remote client computers. It can act as a VPN endpoint for IPsec
connections, for example from a remote office to a central office (“site-to-site”). It
cannot act as a VPN server to terminate IPsec connections from remote client
computers.
