L2TP Server
Path: VPN > L2TP VPN > L2TP Server
A L2TP VPN can be established through this router. Once enabled a L2TP server is available on the router for LAN
and WAN L2TP client users to access. Once the L2TP server is enabled, PPTP clients that are within the range of
configured IP addresses of allowed clients can reach the router’s L2TP server. Once authenticated by the L2TP
server (the tunnel endpoint), L2TP clients have access to the network managed by the router.
The range of IP addresses allocated to L2TP clients can coincide with the LAN subnet. As well the L2TP server
will default to local L2TP user authentication, but can be configured to employ an external authentication server
should one be configured.
