What is Inbound Subnet Aliasing?

For each WAN port configured in the “Static IP” mode, there is an option to activate “Inbound Subnet Aliasing”. If this option is enabled, the BBNA device will act as a proxy in the ARP protocol for all IP addresses in the IP address range specified by the given IP address and subnet mask. This may be necessary in order for inbound traffic from the Internet to reach all of the devices in the specified subnet.
