21.9 ISDN Theft Protection
With the ISDN theft protection function, you can prevent a thief who has stolen a gateway
from gaining access to the gateway owner's LAN. (Without theft protection, he could dial in-
to the LAN by ISDN if the field setting
WAN
->
In Dialup
->
ISDN
->

Always on
is
enabled.)
21.9.1 Options
All interfaces for which the theft protection is enabled are administratively set to "down"
when the gateway boots.
The gateway then calls itself by ISDN and checks its location. If the configured ISDN call
numbers differ from the numbers dialled, the interfaces remain disabled.
If the numbers agree, the device assumes that it is at the original location and the inter-
faces are administratively set to "up".
To reduce cost, the function uses the ISDN D channel.
Note
Note that the ISDN theft protection function is not available for Ethernet interfaces.
