If the remote secure gateway has a static WAN IP address, enter it in the Secure Gateway
Address field. You may alternatively enter the remote secure gateway’s domain name (if it has
one) in the Secure Gateway Address field.
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
ZyXEL Device 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. This may be useful for telecommuters initiating a VPN tunnel to the company
network (see
Section 14.18 on page 207 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.
