PPTP Connection - LAN to LAN
Connection Name: A user-dened name for the connection.
Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN
server, e.g. your ofce server), check Dial In if you want it to operate as a VPN server.
When conguring your router as a Client, enter the remote Server IP Address (or Hostname)
you wish to connect to.
When conguring your router as a server, enter the Private IP Address Assigned to Dial in
User address.
Peer Network IP: Enter the Peer network IP address.
Netmask: Enter the subnet mask of the 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, allows the router to determine which authentication type to
use. You can also 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. This
presents challenges at different periods to ensure that an intruder has not replaced the client.
Data Encryption: Data sent over the VPN connection can be encrypted by a MPPE algorithm.
Default is Auto, which means this setting is negotiated when establishing a connection. You can also
manually Enable or Disable encryption.
Key Length: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits. Default is Auto,
it is negotiated when establishing a connection. 128 bit keys provide stronger encryption than 40 bit
keys.
Mode: You may select Stateful or Stateless mode. The key will be changed every 256 packets when
you select Stateful mode. If you select Stateless mode, the key will be changed in each packet.
Idle Timeout: Auto-disconnect the VPN connection when there is no activity on the connection for
a predetermined period of time. 0 means this connection is always on.
