Gateway Policy
Information
My ZyWALL When the ZyWALL is in router mode, enter the WAN IP address or the domain
name of your ZyWALL or leave the field set to 0.0.0.0.
The ZyWALL uses its current WAN IP address (static or dynamic) in setting up the
VPN tunnel if you leave this field as 0.0.0.0. If the WAN connection goes down, the
ZyWALL uses the dial backup IP address for the VPN tunnel when using dial
backup or the LAN IP address when using traffic redirect.
The VPN tunnel has to be rebuilt if this IP address changes.
When the ZyWALL is in bridge mode, this field is read-only and displays the
ZyWALL’s IP address.
