L2TP Connection - LAN to LAN
L2TP VPN Connection
Name: A given name for the connection
Connection Type: Remote Access or LAN to LAN.
Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN
server, e.g. your office server), check Dial In to have it operate as a VPN server.
When configuring your router to establish a connection to a remote LAN, enter the remote Server
IP Address (or Hostname) you wish to connect to.
When configuring your router as a server to accept incoming connections, enter the Private IP
Address assigned to the Dial in User.
Peer Network IP: Enter Peer network IP address.
Netmask: Enter the subnet mask of peer network based on the Peer Network IP setting.
Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you
are a Dial-In user (server), enter your own username.
Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are
a Dial-In user (server), enter your own password.
Authentication Type: Default is Auto if you want the router to determine the authentication type to
use, or else manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP
(Password Authentication Protocol) if you know which type the server is using (when acting as a
client), or else the authentication type you want clients connecting to you to use (when acting as a
server). When using PAP, the password is sent unencrypted, whilst CHAP encrypts the password
before sending, and also allows for challenges at different periods to ensure that the client has not
been replaced by an intruder.
Tunnel Authentication: This enables router to authenticate both the L2TP remote and L2TP host.
This is only valid when L2TP remote supports this feature.
Secret: The secure password length should be 16 characters which may include numbers and
characters.
