ZyWALL 1050 Support Notes

1.4.3 Star-Mesh Mixed Topology

Taipei

In a Star-mesh mixed VPN topology, ZyWALL 1050 acts as a regional central site

(enabling Hub & Spoke VPN) and spoke sites can be any model of ZyWALL series. The

Star – Mesh Mixed Topology is well suited for an enterprise having a regional operation

center acting as a regional hub and spoke VPN network in the area. The connection between

each regional operation center will be backbone VPN tunnel. To ensure the communication

continuity, we can use VPN HA (secondary security gateway) to configure a backup VPN

tunnel in case the primary VPN connection failure.

We use the below presented network topology to explain how to configure Star-Mesh

Mixed Topology between all the ZyWALL series devices. The ZyWALL 1050s act as a

Regional Center devices whereas ZyWALL 2 Plus, 5, 35 and 70 are the regional remote sites’

devices which are building VPN tunnel back to the Regional Center and provide connection

with the other area remote nodes via the VPN tunnel between the two Regional Centers.
