The OpenCom 510 in a LAN-to-LAN link
In the Configurator, NET Configuration: Branch menu you can configure the
dial-in settings. The OpenCom 510 will set up a connection whenever a IP data
transfer to the other LAN is requested.
Note that such a connection is only set up when specific requests are made. These
can be for FTP file transfers, e-mails or downloading Web pages. Name resolution
via broadcasts is not possible. If you wish to use the LAN-to-LAN link to access files
and printers in the Windows network, you need an IP-enabled server that admin-
isters the name resolution for the Windows network.
As the IP address range, you can select one of the 256 class C subnetworks
designed for local LANs. Select a class C sub-network in the range from 192.168.0.0
to 192.168.255.0.
9.6 Useful Information on Internet Access
9.6.1 Costs
The OpenCom 510 uses a router function to access the Internet, which means that
it automatically establishes an Internet connection when required and terminates
the connection after a certain period of time if no data are being transmitted.
Unfortunately, programs other than those typically intended to access the Internet
(such as your browser or your e-mail software) may send out data packets which
cause an Internet connection to be established, even if these programs are not
strictly Internet-associated applications.
