account on the addressed server for network log-in. If you use the same log-in
name for the Forum 523/524 user account and the same password for the
network log-in, you have to enter this combination only once when dialling in.
Note:
In a larger Windows network with several segments, the lists of
computer names visible in the network environment can no
longer be established by broadcasts. In this case you use a
special WINS server whose address the Forum 523/524 does
not make known to the workstation computer when dialling in
with IPSEC or ISDN. For this reason, you enter the address of a
WINS server manually in the network settings of the work-
station.

You can use the Forum 523/524 to interlink two LANs via ISDN or via an
encrypted VPN connection (Virtual Private Network).
In case of a VPN connection, both Forum 523/524 systems use an Internet
connection to transfer data. For encryption, the protocols PPTP (Point to Point
Tunneling Protocol) and IPSec (Secured IP) can be used.
In case on an ISDN connection, you configure two Forum 523/524 systems so
that they can dial in to each other.
In order for this to work, the two LANs must be configured for different IP
address ranges (subnetworks). For at least one of the Forum 523/524
systems, change the prescribed address range for the LAN.
