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 (IP_200.200.200.1) and 
WAN2 (IP_100.100.100.1) on BiGuard 30. Remote PCs are attempting to access the 
servers via the Internet by making a DNS request, entering a URL 
(www.mydomain.com). Using a load balancing algorithm, BiGuard 30 can direct 
incoming requests to either WAN port based on the amount of load each WAN port 
is currently experiencing. If WAN2 is experiencing a heavy load, BiGuard 30 
responds to incoming DNS requests with WAN1. By balancing the load between 
WAN1 and WAN2, your BiGuard 30 can ensure that inbound traffic is efficiently 
handled, making sure that both ports are equally sharing the load and preventing 
situations where service is slow because one port is completely saturated by 
inbound traffic. 
 
Please refer to appendix H for example settings. 
 
A typical scenario of how traffic is directed with DNS Inbound Load Balancing is 
illustrated below:
