Appendix B

Using serial PPP

You use Serial Point-to-Point Protocol (PPP) to manage the VPN Router from a remote location using PPP and the serial interface. If the VPN Router becomes unreachable over the Internet, you can still dial up and manage it through the serial interface menu.

With this feature, the serial interface becomes like a private WAN interface. You can manage through it or even tunnel through it. You can enable Serial PPP support on the System > Settings window. When configuring Serial PPP, you can set the VPN Router to Auto Detect, or you can specify that either PPP or the Serial Menu are the options available through the serial port.

The Password Authentication Protocol (PAP) performs Serial PPP authentication, which uses a standard user ID and sends a password in the clear. When authenticated, the serial interface acts like a private WAN interface.

Establishing a serial PPP connection

To enable Serial PPP:

1Set up a Dial-Up Networking connection.

2Set up the modem.

3Set up the VPN Router.

4Dial into the VPN Router using the Primary Administrator’s user name and password.
