SHDSL VPN Firewall Bridge/Router
Chapter 4: Configuration
PPTP Connection - Remote Access
Connection Name: 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 operates as a VPN server.
When configuring your router as a Client, enter the remote Server IP Address (or Domain
Name) 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 an intruder has not replaced the client.
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.
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 Time: 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.
Active as default route: Commonly used by the Dial-out connection which all packets will route through
the VPN tunnel to the Internet; therefore, active the function may degrade the Internet performance.
