ZyWALL 1050 Support Notes

Branch Office

The network topology below is used to illustrate this application. We used ZyWALL70 as

branch office gateway which is connected to the main office’s ZyWALL1050 A. All the

outgoing traffic from the branch office including the internet traffic and the remote subnet

traffic will be send to the VPN tunnel and handled by ZyWALL1050 A. ZyWALL1050 uses

WAN1 to establish VPN connection with ZyWALL70 in remote office and WAN2 as an uplink

to the ZyWALL1050 B which is the internet connection gateway of main office. Thus,

ZyWALL1050 A will route the traffic from the VPN tunnel and send it to the appropriate place

of the packet destination.
