PPTP Connection - Remote Access
(BiPAC 8500/ 8501/ 8520 Only)
• Connection Name: A user-defined name for the connection (e.g. “connection to office”).
• 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 if you want the router to
operate as a VPN server.
o
When configuring your router as a Client, enter the remote Server IP Address (or
Domain Name) 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.
• Authentication Type: Default is Auto if you want 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.
