Frequently Asked Questions
Question: You have just configured the Forum 523/524 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 connecting via the dial-up network.
Question: Our network has grown over time, with several segments
connected by one central router. How can PCs from all segments connect
to the Forum 523/524?
If several routers are configured for your network in different segments, you
can enter extra static routes in the
Network: Routes
menu.
Question: In our network the Forum 523/524 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 server PCs. Make the appro-
priate host assignment entries in the Configurator (
Network
:
Hosts
menu).
Create a static DHCP entry for each host assignment in the
Network
:
DHCP
menu. Activate “Dynamic and static address” for the DHCP server.
Internet
Question: 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
Network
:
LAN
menu.
Question: 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 translation process.
It is possible to redirect incoming connections in the
Configurator
, menu
Network
:
Port Forwarding
. You should secure the redirection target (PC or
server) with a suitable firewall software.
