Appendix C - VPNs

Connecting 2 LANs via VPN

Figure 98: 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 ADE-4300/ADW-
4300.

Figure 99: Connecting 2 ADE-4300/ADW-4300s

Note

•

The LANs MUST use different IP address ranges.

•

Both endpoints have fixed WAN (Internet) IP addresses.

•

This example uses an "Auto" policy, using IKE
