under the
/Setup/WAN-module/Security
menu. You have a
choice of the following:
All calls are accepted from any remote station.
Name: Only calls from those remote stations entered in the name list are
accepted.
Number: Only calls from those remote stations entered in the number list
are accepted.
Name or number: Only calls from those remote stations entered in the
name list
or number list are accepted.
It is an obvious requirement for identification that the corresponding informa-
tion is also sent by the caller.
Verification of
name When using the ELSA or PPP layer on the B channel, the name of the calling
party can also be transmitted. This requires a connection to be established
first, since the name cannot be transferred over the D channel.
The name of the remote station can also be transferred in PPP connections.
This requires a connection to be established first, since the name cannot be
transferred over the D channel.
The routers' response is obvious: Only those calls with recognized names are
accepted if protection by name is set; all others are rejected.
The name sent by the remote station will be checked for its appearance on
the PPP list of user names if the PPP protocol is being used. If the user name
is not available, the device name is accepted and verified as the name of the
remote station. The PPP list can be found in the
ELSA LANconfig in the 'Com-
munication' configuration section on the 'Protocols' tab, or in the
/Setup/WAN-module/PPP-list
menu.
Addition security is provided by a password. PPP offers password protection
through three different login protocols: PAP (Password Authentication Proto-
col), CHAP (Challenge Handshake Authentication Protocol) and MS-CHAP
(the Microsoft variation of CHAP). All of these protocols serve the same pur-
pose. The calling device determines which protocol is used.
Obviously you will not need to use the PAP, CHAP or MS-CHAP security pro-
cedures if you are using the LANCOM Wireless to dial up an Internet service
provider yourself, for example. You will probably not be able to persuade the
ISP to respond to a request for a password.
And where do a caller's name and password come from?
