In this page, you need to enter the PPP Username and PPP Password.
PPP Username: The correct user name that your ISP provides to you.
PPP Password: The correct password that your ISP provides to you.
Authentication Method: The value can be AUTO, PAP, CHAP, or
MSCHAP. Usually, you can select AUTO.
Enable Fullcone NAT: A full cone NAT is one where all requests from the
same internal IP address and port are mapped to the same external IP
address and port. Furthermore, any external host can send a packet to the
internal host, by sending a packet to the mapped external address.
Dial on demand (with idle timeout timer): If this function is enabled, you
need to enter the idle timeout time.

the PC being attached to the modem (at this time, the modem connects to
only one PC).
