Connecting 2 LANs via VPN
Figure 81: Connecting 2 VPN Gateways
This allows two (2) LANs to be connected. PCs on each endpoint gain secure access to the
remote LAN.
• The 2 LANs MUST use different IP address ranges.
• The VPN Policies at each end determine when a VPN tunnel will be established, and what
systems on the remote LAN can be accessed once the VPN connection is established.
• It is possible to have simultaneous VPN connections to many remote sites.
VPN Example
In this example, 2 LANs are connected via VPN. Each end has a Wireless ADSL Router.
