19.4 Secure Gateway Address

Secure Gateway Address is the WAN IP address or domain name of the remote IPSec router
(secure gateway).
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
Prestige 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).

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