Address
Information
My IP Address Enter the WAN IP address of your ZyXEL Device. The VPN tunnel has to be
rebuilt if this IP address changes.
The following applies if this field is configured as 0.0.0.0:
The ZyXEL Device uses the current ZyXEL Device WAN IP address (static or
dynamic) to set up the VPN tunnel.
If the WAN connection goes down, the ZyXEL Device uses the dial backup IP
address for the VPN tunnel when using dial backup or the LAN IP address when
using traffic redirect. See the chapter on WAN for details on dial backup and traffic
redirect.
Secure Gateway

Type the WAN IP address or the URL (up to 31 characters) of the IPSec router
