ZyXEL Communications ZYWALL USG 2000 Support Notes page 75

The ZyWALL USG2000 supports Star topology via the VPN concentrator feature. The
VPN concentrator can help to reduce the VPN tunnel numbers and allows centralized VPN
tunnel management.
The topology used for our VPN concentrator guide.
This topology is designed to simulate a global VPN network deployment. The company has
a global headquarters in Taiwan and other offices around the world.
This company decided to build up a VPN concentrator to let all the offices' internal network to
be shared and interconnected based on a security link.
We will separate each group as a member of each office and build up the VPN tunnel with
headquarter and then to route the VPN traffic across the HQ to the destination office's internal
network.
