Chapter 7: Connecting two networks
7 Connecting two networks
Network connectivity, also known as LAN-LAN connectivity, with the
LANCOM Router is used for interconnecting two local area networks. Con-
necting LANs over VPN ensures that the Internet-based connection between
the two LANs has high-security protection. Each LAN must be equipped with
a VPN-capable router.
Setting up LAN-LAN connectivity is carried out with the familiar convenience
of a Setup Wizard.
Always configure both ends
Both of the routers for LAN-LAN connectivity must be configured. Note that
the configuration information at both ends must match.
Security aspects
Of course your LAN has to be protected from unauthorized access. For this
reason, a LANCOM provides a range of security mechanisms that offer an out-
standing level of protection. VPN-based connectivity relies on IPsec for trans-
ferring data. The encryption methods employed are 3-DES, AES or Blowfish.

Which details are necessary?
The Wizard requests you for all of the necessary details step by step. If possi-
ble, you should have all of this information to hand before you start the Wiz-
ard.
The significance of the information required by the Wizard can be explained
by an example: Connectivity between a branch office and your main office.
The two routers are named 'MAIN OFFICE' and 'BRANCH OFFICE'.
The following tables indicate which entries are to be made for each of the two
routers. Paths show how the entries relate to one another.

General information
The following information is required for setting up LAN-LAN connectivity.

The following instructions assume that LANCOM Routers are being
operated at both ends. It is possible to set up network connectivity
between routers from other manufacturers. However, this mixed con-
figuration frequently requires far-reaching modifications to both
devices. In cases like this refer to the Reference Manual.
