Appendix C - VPNs
Connecting 2 LANs via VPN
Figure 77: 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.
