INDUSTRIAL 4G LTE CELLULAR ROUTER - UM V1.1.8
115
11.2.6 IPsec > Hub-Spoke Topology
This section explains how to set Hub-Spoke Topology and connect two (or more) gateways to a
central one.
This requires one connection between each spoke and the central hub (n - 1 connections for n
gateways)
For example, in the Hub-and-Spoke topology, we want to send the essential traffic through IPsec
VPN tunnel. Thus, we will set the Route-based VPN and Static Route to handle this situation. The
Route-based VPN will redirect the traffic which is matching the routing table only to IPsec VPN
tunnel.
After setting some configurations, the PC1 and PC2 could communicate each other through the
Hub gateway.
