The purpose is to setup a VPN trunk between Vigor3200 (192.168.1.0/24) and Vigor3300
(192.168.33.0/24).
At present, Vigor3200 just supports one VPN trunk group with two members for the same
VPN network pair. In this case, the VPN trunk is built for 192.168.1.0/24 <-> 192.168.33.0/24.
In other word, although Vigor3200 supports 4 WAN connections, it just allows you to use 2
VPN connections over two WAN ports for one VPN trunk group between the networks
192.168.1.0/24 and 192.168.33.0/24.
Note:
You can still setup two VPN trunk groups over 4 WAN connections between the
networks 192.168.1.0/24 and 192.168.33.0/24. But the VPN traffic can just pass
through one VPN trunk group.
You can create arbitrary number of VPN trunk groups between Vigor3200 and
Vigor3300 for different VPN network pairs. For example, suppose there is another
network (192.168.10.0/24) behind Vigor3300. You may create a VPN trunk group
over WAN1 and WAN2 connections for 192.168.1.0/24 <-> 192.168.33.0/24, and the
other VPN trunk group over WAN3 and WAN4 for 192.168.1.0/24 <->
192.168.10.0/24. Please refer to the Scenario 2 described in this document later.
Vigor3200 as a VPN client (dial out site),
LAN: 192.168.1.0/24
WAN 1 IP: 202.211.110.30 (My GRE IP, 10.0.0.1, Peer GRE IP, 10.0.0.2)
WAN 2 IP: 202.211.120.30 (My GRE IP, 10.0.0.3, Peer GRE IP, 10.0.0.4)
Vigor3300 as a VPN server (dial in site),
LAN: 192.168.33.0/24
WAN 1 IP: 202.211.110.100 (Local GRE IP, 10.0.0.2, Remote GRE IP, 10.0.0.1)
WAN 2 IP: 202.211.120.100 (Local GRE IP, 10.0.0.4, Remote GRE IP, 10.0.0.3)
