19.5 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.
It is possible to redirect incoming connections in the Configurator, menu NET
Configuration: Port Forwarding. You should secure the redirection target (PC or
server) with a suitable firewall software.
It is not possible to access the Internet with the OpenPhone 27.
The requirement for this is that the set should be configured as Handset+data.
The telephone number used by the OpenPhone 27 to establish an Internet con-
nection must also be specified in the respective user profile (Configurator, User
Manager: User menu).
With the OpenPhone 27, the Internet can be accessed either directly via the
remote data transfer network or indirectly via RAS access on the OpenCom 510.
For direct access you can directly dial any provider. Indirect access uses the routing
function of the OpenCom 510, accompanied by the configured security features,
for example.
Directly via remote data transfer network
If the Internet is accessed directly via the remote data transfer network, make sure
that
■ the remote data transfer network is properly installed on your PC and that the
correct ISP access data is configured,
