L2TP VPN
Layer Two Tunnelling Protocol (L2TP) is an extension of the PPTP protocol used
to enable a virtual private network (VPN) over the Internet. L2TP combines
the best features of PPTP from Microsoft and L2F from Cisco Systems. The L2TP
itself does not provide any encryption or confidentiality but can rely on an
encryption protocol that it passes within the tunnel, such as IPSec, to provide
security.
L2TP Sever
The Universal Hub can be configured as a L2TP server. When L2TP Sever is
selected for a VPN tunnel, the following settings will be shown:
Tunnel name
: a name of the tunnel used for identifying tunnels.
Authentication
: the authentication method used by the L2TP VPN. The
options include: PAP, CHAP, MS-CHAPv1, and MS-CHAPv2. The option
cannot be left as NONE.
Local IP Address
: the local IP address of the L2TP Tunnel. It has to be
different from the device LAN IP, e.g. 10.2.0.1.
