Setp 1: Setup VPN in branch office A

Because VPN routing enables branch offices to talk to each other via tunnels

concentrated on headquarter. In this step, we configure an IPSec rule in

Prestige (Branch_A) for PCs behind branch office A to access both LAN

segments of headquarter and branch office B. Because the LAN segments of

headquarter and branch office B are continuous, we merge them into one

single rule by including these two segments in Remote section. If by any

chance, the two segments are not continuous, we strongly recommend you to

setup different rules for these segments.

Create a VPN Rule with name Branch_A. The configuration is the same as

Prestige to Prestige Tunnel, just the IP Address is a little different:

(1) Local Address Type is Range Address and IP Address Start is

192.168.3.0, IP Address End is 192.168.3.255. This section covers the LAN

segment of branch office A.
