Modem Fundamentals

The modem allows connections to be made over standard telephone lines. PPP is used to run network traffic over a modem link.

PPP Mode Fundamentals

PPP (Point-to-Point Protocol) is a protocol for linking two systems over a serial line.

As your PPP connection is established a PPP interface will be created. The name will be “ppp0”. Use this interface name in firewall rules.

Authentication, Addresses and DNS Servers

PPPauthentication utilizes PAP or CHAP. Your ISP will provide you with a user-ID and password along with a phone number which you will enter in the GUI. The authentication process will assign a local IP address and addresses of the ISPs DNS servers to the router. You should use these DNS servers unless you wish to provide your own.

You will obtain either a dynamic or static IP from your ISP. Firewall configuration should be performed as is appropriate.

When the Modem Connects

The modem may be configured to connect at boot time.

LED Designations

The RuggedRouter provides a pair of LEDs to indicate information about the modem PPP connection.

PPP-Link will be green when the modem PPP link is established. It will flash while a connection is being established, or a console dial in session is active.

PPP-Data will flash green when there is traffic on the PPP link.
