L2TP Connection - Remote Access
L2TP VPN Connection
• Connection Name: User-defined name for the connection (e.g. "connection to office").
• Type: Check the Dial Out radio button if you want your router to operate as a client
(connecting to a remote VPN server, e.g. your office server), check the Dial In radion
button if it is to operate as a VPN server.
o When configuring your router as a Client, enter the remote Server IP Address (or
Hostname) you wish to connect to.
o When configuring your router as a server, enter the Private IP Address Assigned
to Dial in User address.
• 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.
• PPP Authentication Type: Default is Auto if you want the router to determine the type
of authentication 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 the authentication type you want
clients to use (when acting as a server). When using PAP, the password is sent
unencrypted, whilst CHAP encrypts the password before sending, and this presents
challenges at different periods to ensure that the client has not been replaced by an
intruder.
