Forum 523/524 in a Serverless LAN92
Configuration Examples
RAS Access
You can establish a connection to the Forum 523/524 from an
external PC via a VPN connection or via an ISDN card.
VPN (Virtual Private Networking) is a technology to connect an
external PC over an existing Internet access using a secured and
encrypted data connection. A prerequisite is the permanent inter-
net access of the Forum 523/524. As an alternative, the “ISP trig-
ger call” can be configured. To secure the data connection, the
protocols PPTP and IPSEC are available. PPTP encryption is
optional.
The necessary IP settings are transmitted by the Forum 523/524
on establishment of the connection. The computer that has dialled
in has access to all services in the LAN that can be used via the IP
protocol. The authorisation for RAS access is set up in the Config-
urator via the User Manager: User Groups menu.
The technical properties of the connection can be configured in the
Configurator via the Network: RAS menu. Select one of the
offered connection protocols (ISDN, PPTP or IPSEC). Further
information can be found in the online help of the web console.
In a serverless LAN, Windows uses the NetBIOS protocol for
accessing files and printers via the network environment. NetBIOS
can use NetBEUI, IPX/SPX or IP as the transport protocol. In the
network environment, you can only access files and printers on
workstations using IP for NetBIOS.
