17.4 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 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).

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 (seeSection 17.18 on page 244for 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.

17.5 VPN Setup Screen

The following figure helps explain the main fields in the web configurator.

Figure 120 IPSec Summary Fields

Local and remote IP addresses must be static.

Click Security and VPN to open the VPN Setup screen. This is a read-only 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.
