LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN Chapter 5: Linking two networks 5 Linking two networks With the network interconnection (also known as LAN to LAN coupling) of the LANCOM Router, two local networks are linked. The LAN to LAN coupling can be realized in principle in two different ways: EN VPN: For coupling via VPN, the connection between both LANs is established over a specially secured connection through the public Internet. A router with VPN support is required in both LANs.
LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN Chapter 5: Linking two networks What information is necessary? The wizard will prompt you for the necessary information on a step-by-step basis. If possible, however, you should have it available before launching the wizard. To explain the significance of the information requested by the wizard, we will be using a typical deployment as an example: setting up a link between a branch office and its headquarters.

LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN The password for the ISDN connection is an alternative to the use of the ISDN caller ID. It is always used to authenticate callers that do not send an ISDN caller ID. The exact same password must be entered on both sides. It is used for calls in both directions. The Shared Secret is the central password for security within the VPN.
LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN Chapter 5: Linking two networks 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. EN 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'.
LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN Chapter 5: Linking two networks The IPX network numbers in the head and branch offices are specified to the respective remote sides.
