Frequently Asked Questions Internet

You have just configured the OpenCom 100 via the network. Why is it not
possible now to establish a remote data transfer network connection?
The network card and the communication (remote data transfer) adapter cannot
be run with the same routing setting. Deactivate the network card before con-
necting via the dial-up network.
Our network has grown over time, with several segments connected by one
central router. How can PCs from all segments connect to the OpenCom 100?
If several routers are configured for your network in different segments, you can
enter extra static routes in the NET Configuration: LAN: Routes menu.
In our network the OpenCom 100 dynamically issues the IP addresses by
DHCP. Can I firmly assign the IP address for our internal server PCs (mail,
Web)?
You need a static address assignment for these PCs. Make the appropriate host
assignment entries in the Configurator (NET Configuration: LAN: Hosts menu).
Create a static DHCP entry for each host assignment in the NET Configuration:
LAN: DHCP Server menu. Activate “Dynamic and static address” for the DHCP
server.
18.5 Internet
I cannot access our company Web site.
Outside your system, your company Web site is accessed at “www.firm.com”, but
in the Configurator you have entered “firm.com” as the domain. Your company’s
site URL thus counts as an internal URL and can only be accessed by entering the
direct IP address. If required, change the domain setting in the NET Configu-
ration: LAN menu.
Why do some Internet services not work even though they can be used when
dialling in directly via a modem?
Some Internet services require an active connection coming from the Internet. But
the configured filter rules prevent this. Plus, it is not possible to establish incoming
Internet connections with the PCs directly owing to the network address trans-
lation process.
