After configuring VPN settings on the local ZyWALL 2 Plus, you must also create a VPN 

tunnel on the remote VPN gateway to connect from the central office to the ZyWALL 2 Plus 

in the branch office. If you are using ZyWALL 70 or ZyWALL 35 as the remote VPN 

gateway, you also get the redundant WAN/VPN feature. In this case, enter 0.0.0.0 in the My 

IP Address field to set the system to automatically detect the IP address of the active WAN 

interface. Thus if the primary WAN interface is down, the My Address field is the IP address 

of the secondary WAN interface.

ZyWALL can inspect the VPN packet before encrypt or after decrypt the packet sending to or receiving 

from VPN tunnel.
