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. This may be useful for telecommuters initiating a VPN tunnel to the company
network. See the Telecommuter VPN/IPSec Examples section
