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
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.

Local and remote IP addresses must be static.
Click Security > VPN to open the VPN Setup screen. This is a menu of your IPSec rules 
(tunnels). The IPSec summary menu is read-only. Edit a VPN by selecting an index number 
and then configuring its associated submenus.
