Internet Access
You can also use the Forum 523/524 as an Internet access server
in a LAN with an IP-enabled server. To do this, you must enter the
Forum 523/524 IP address on the server as the default gateway.
In addition, you must edit the internal DNS server configuration
so that the resolution of external DNS names is forwarded to the
Forum 523/524.
In this example, the Internet connection is established from a
workstation computer via the server, which in turn requests Inter-
net access from the Forum 523/524.
There are two different ways of suitably configuring the internal
DNS server. You can enter the Forum 523/524 IP address as a
DNS forwarder. If you require access to extended DNS informa-
tion, you can also configure the DNS server for a recursive DNS
request without the DNS forwarder. For further explanation, refer
to the DNS server documentation.
