In the case of PPP, a user name (and in conjunction with PAP, CHAP or MS-CHAP, a password) is sent to the remote station during connection establishment. When a computer dials into the LANCOM, the communications software, for example Windows Dial-Up Network, prompts the user for the user name and password to be transferred.
If the router establishes the connection itself, for instance, to an ISP, it is using the user name and password from the PPP list. If no user name is listed there, the device name is used in its place.
The PPP list can be found as follows:
LANconfig: Communication / Protocols / PPP list
WEBconfig: LCOS menu tree / Setup / WAN / PPP-list
In addition, the PPP protocol also permits the caller to require an authentication from the remote station. The caller then requests a user or device name and password from the remote station.
