Note:
To access the OpenCom 510 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.
10.4.2
Internet Access
You can also use the OpenCom 510 as an Internet access server in a LAN with an
IP-enabled server. To do this, you must enter the OpenCom 510 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 510.
In this example, the Internet connection is established from a workstation via the
server, which in turn requests Internet access from the OpenCom 510.
There are two different ways of suitably configuring the internal DNS server. You
can enter the OpenCom 510 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 request without the DNS forwarder. For further explanation, refer to the DNS
server documentation.
