Prestige 2602HW Series User’s Guide
•If the WAN connection goes down, the Prestige uses the dial backup IP address for the VPN tunnel when using dial backup or the LAN IP address when using traffic redirect. See the chapter on WAN for details on dial backup and traffic redirect.
17.4Secure 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).
17.4.1 Dynamic Secure Gateway Address
If the remote secure gateway has a dynamic WAN IP address and does not use DDNS, enter
0.0.0.0as 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 17.18 on page 225 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.
