There are three pages under VPN in the MG7540 configuration manager: IPsec,
L2TP/PPTP and Event Log. Use the IPsec page to set up an endpoint for a site
to site IPsec connection. Use the PPTP/L2TP page to set up a server for a set of
remote clients that connect via PPTP or L2TP. You may find the Event Log
useful to determine what has gone wrong if you have trouble setting up a VPN.
For details on how to configure a VPN on the MG7540, follow the help available
through the information icons on the configuration manager pages.
When the MG7540 is configured as a VPN endpoint, devices that connect to the
endpoint will need to know the IP Address of the MG7540. You can find this
address on the StatusConnections page. To provide the most stable VPN
connections, the MG7540’s router should be provisioned with a static IP
Address. You will need to order this from your cable service provider.
The VPN implementations on the MG7540 are best effort. They are also
Windows-centric. You will have to verify suitability for your own environment.
