What information is necessary?
6-5
Unlike when accessing the Internet, all of the IP addresses in the
involved networks are visible on the remote side when coupling
networks, not just those 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 in
the headquarters and can access it (assuming it has the appropriate
rights), and vice versa.
6.1.2.1 DNS access to the remote LAN
Thanks to DNS, it is not only possible to access remote computers in
a TCP/IP network via their IP address, but also by using freely
defined names.
For example, the computer with the name 'pc1.branch.company' (IP
10.0.2.10) will not only be able to access the server of the head office
via its IP address, but also via its name, 'server.head.company'. The
only precondition: the domain of the remote network in the wizard
must be specified.
The domain can only be specified in the LANconfig wizard. In
WEBconfig, enter the appropriate information later in the expert
configuration. For more information, see the SwyxConnect reference
manual.
6.1.2.2 Extranet VPN
Finally, one can decide whether access to local stations is permitted.
In this 'Extranet VPN' operating mode, the IP stations do not expose
LAN of head office.
