2.4.1Inbound Fail Over
Configuring BiGuard 50G for Inbound Fail Over allows you to ensure that incoming traffic is uninterrupted by having BiGuard 50G default to WAN2 should WAN1 fail.
In the above example, an FTP Server (IP_192.168.2.2) and an HTTP Server (IP_192.168.2.3) are connected to the Internet via WAN1 (ftp.billion.dyndns.org) on BiGuard 50G. A remote computer is trying to access these servers via the Internet. Under normal circumstances, the remote computer will gain access to the network via WAN1. Should WAN1 fail, Inbound Fail Over tells BiGuard 50G to reroute incoming traffic to WAN2 by using the Dynamic DNS mechanism. Configuring your BiGuard 50G for Inbound Fail Over provides a more reliable connection for your incoming traffic.
Please refer to appendix H for example settings.
