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.
