Auth. Protocol: Manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP
(Password Authentication Protocol) if you know which authentication type the server is using (when
acting as a client), or the authentication type you want the clients to use when tehy are connecting to
you (when acting as a server). When using PAP, the password is sent unencrypted, while CHAP
encrypts the password before sending, and also allows for challenges at different periods to ensure
that an intruder has not replaced the client.
PIN: PIN stands for Personal Identification Number. A PIN code is a numeric value used in certain
systems as a password to gain access, and authentication. In mobile phones a PIN code locks the
SIM card until you enter the correct code. If you enter the PIN code incorrectly into the phone 3 times
in a row, then the SIM card will be blocked and a PUK code will be required from your network / service
provider to unlock it.
Note: when the 3G SIM card is pulled out and then insert into again, you should again press Apply
button to make 3G connection take effort, or you can Save config and Restart the route to reach the
same effort.
