mechanisms in PPP, firewall filters and IP masquerading complete the secu-
rity concept. Furthermore, login barring prevents any “brute force attacks”
and denies access to the router after a configurable number of login attempts
using an incorrect password.
Wireless and secure with WEP
The WEP (

rivacy) encryption method attaches a 40-bit or
128-bit key to the wireless data. The data encryption and authentication of
the stations makes it as good as impossible for the data in transit to be inter-
cepted. This ensures a considerably higher level of data security in wireless
network operation. Additionally, station filters based on MAC addresses
make it possible to allow or deny individual stations access to the access
point.
Charge monitoring
Subscribing to “Advice of charge during connection” on the ISDN network
(AOCD) allows you to set the charge units available for a specified period for
the ISDN connection. This puts you in constant control of your phone bill.
If charge information is not available from your ISDN connection, you can also
limit the active ISDN connect time for a specified period. The router will not
permit the active establishment of connections once this time has elapsed.
Least-cost routing
Even if there is a large selection of telecommunications service providers you
can always use the cheapest ISDN lines using the least-cost router.
Automatic time check
In order to generate sound statistics and to select the correct connection
paths using the least cost router, the device always must have the exact time.
It can read the time from the ISDN network itself. The router's internal time
is always compared to ISDN time either each time a connection is estab-
lished or each time the device is switched on. Of course, the time can also be
set manually.
Channel bundling and compression
The device supports static and dynamic channel bundling via MLPPP and
BACP on the ISDN line. Stac data compression (hi/fn) can be used to achieve
increases in the data transfer rate of up to 400%.
