Chapter 4: Configuration 69
PPTP Connection - LAN to LAN
Connection Name: A user-define description of the connection.
Type: Check Dial Out if you want your gateway to operate as a client (connecting to a remote VPN server,
e.g. your office server), check Dial In operates as a VPN server.
When configuring your gateway as a Client, enter the remote Server IP Address (or Hostname)
you wish to connection to.
When configuring your gateway as a server, enter the Private IP Address Assigned to Dial in
User address.
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 the your Host. If you are a
Dial-In user (server), enter your own password.
PPP Authentication Type: Default is Auto if you want the gateway to determine the authentication type to
use. You can also manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP
(Password Authentication Protocol) if you know which type of authentication method the server is using.
The password is sent unencrypted when using PAP. CHAP encrypts the password before sending and also
allows for challenges at different periods to ensure that an intruder has not taken the client’s place.
Data Encryption: An MPPE algorithm can encrypt Data sent over the VPN connection. Default is Auto, so
that 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 .
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.
