ZyWALL 2 Series User’s Guide

You can also enter a remote secure gateway’s domain name in the Secure Gateway Address field if the remote secure gateway has a dynamic WAN IP address and is using DDNS. The ZyWALL has to rebuild the VPN tunnel each time the remote secure gateway’s WAN IP address changes (there may be a delay until the DDNS servers are updated with the remote gateway’s new WAN IP address).

14.4.1 Dynamic Secure Gateway Address

If the remote secure gateway has a dynamic WAN IP address and does not use DDNS, enter 0.0.0.0 as the secure gateway’s address. In this case only the remote secure gateway can initiate SAs.

The Secure Gateway IP Address may be configured as 0.0.0.0 only when using IKEkey management and not Manual key management.
