ZyWALL Series Internet Security Gateway
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).
15.4.1 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. This may be useful
for telecommuters initiating a VPN tunnel to the company network. See section 15.18 for configuration
examples.
The Secure Gateway IP Address may be configured as 0.0.0.0 only when using IKE
key management and not Manual key management.
