DNS Name Resolution
In a LAN with an IP-enabled server, the latter is also responsible for DNS name reso-
lution. 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 address after a restart, you must
specify this IP address permanently on a DHCP server. On a DHCP server it is possible
to link the MAC address of a network card with a specific IP address. You will find de-
tails in the server documentation.
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 configu-
ration so that the resolution of external DNS names is forwarded to the
OpenCom 100.
The OpenCom 100 as a DNS server in a LAN with an IP server
In this example, the Internet connection is established from a workstation computer
via the server, which in turn requests Internet access from the OpenCom 100.
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 DNS
