8.4.1 DNS Name Resolution
In a LAN with an IP-enabled server, the latter is also responsible for DNS name res-
olution. If you want to start the
Configurator
by entering a DNS name, you must
link this name on the server with the IP address used by the OpenCom 100. For
further information, refer to the server documentation.
Note:
To access the OpenCom 100 under the same IP ad-
dress after a restart, you must specify this IP address perma-
nently on a DHCP server. On a DHCP server it is possible to
link the MAC address of a network card with a specific IP ad-
dress. You will find details in the server documentation.
8.4.2 Internet Access
You can also use the OpenCom 100 as an Internet access server in a LAN with an
IP-enabled server. To do this, you must enter the OpenCom 100 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
OpenCom 100.
In this example, the Internet connection is established from a workstation com-
puter via the server, which in turn requests Internet access from the
OpenCom 100.
The OpenCom 100 as a DNS server in a LAN with an IP server
There are two different ways of suitably configuring the internal DNS server. You
can enter the OpenCom 100 IP address as a DNS forwarder. If you require access to
extended DNS information, you can also configure the DNS server for a recursive
