Billion BIPAC-8500 / 8520 SHDSL VPN Firewall Bridge / Router
Chapter 4: Configuration
Remote Access PPTP Connection
Connection Name:
This allows you to identify this particular 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 operates as a VPN server.
When configuring your router as a Client, enter the remote Server IP Address (or
Hostname)
you wish to connection to.
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
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also allows for challenges at different periods to ensure that the client has not been
replaced by an intruder.
Data Encryption: Data sent over the VPN connection can be encrypted by an MPPE
algorithm. Default is Auto, so that this setting is negotiated when establishing a
connection, or else you can 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.
