LANCOM WLC series

 Chapter 7: Connecting two networks

130

EN

The 

shared secret

 is the central password for the VPN connection's secu-

rity. It must be entered identically at both ends.

7.1.2

Settings for the TCP/IP router

In the TCP/IP network, correct addressing is of extreme importance. For net-
work connectivity, it should be observed that both networks are logically sep-
arated. For this reason they require their own network number (e.g. '10.0.1.x'
and '10.0.2.x'). The two network numbers must be different.

Unlike with Internet access, network connectivity makes all of IP addresses
visible in all participating networks, including those in the remote LAN, and
not just that of the router. The computer with the IP address 10.0.2.10 in the
branch-office LAN sees the server 10.0.1.2 at the main office and, with the
appropriate rights, has access to it. The same applies in the other direction.

DNS access to the remote LAN

Remote computers in a TCP/IP network can be accessed not only with their IP
addresses, but also by freely definable names with the aid of DNS.

For example, the computer named 'pc1.branch_office.company (IP 10.0.2.10)
can access the server at the main office by using its IP address or the name
'server.main_office.company'. There is just one requirement: The domain of
the remote network must be entered into the Wizard.

The domain can only be specified in the LANconfig Wizard. With
WEBconfig, the necessary changes are made later in the Expert Con-
