(Firmware updated to the latest version as of April 28, 2016)
This Firewall is connected to two Windows Server 2012 Standard machines functioning as public web servers. Each machine has a NIC that is dedicated to Network Load balancing (as well as another NIC for non-public access). For each NLB NIC, the FVS318G detects both the unique IP address assigned to the NIC (192.168.1.22 and 192.168.1.23) as well as the IP address assigned to NLB by software - 192.168.1.100. The LAN Groups tab on the FVS318G shows all three IP adresses and shows that they all have the same MAC address - which is to be expected since the MAC address assigned to each NIC gets set by the NLB software; the original MAC address for each of the NLB NICs is hidden. Unfortunately, the NLB software doesn;t hide the unique IP address for each of the NLB NICs. The problem, of course, is that network packets are routed to the IP address identified by the MAC address, and it appears that they get routed to the unique IP address for the first NIC found - and of course, there's no way of priotizing which IP is used first. More relevantly there's no way of deleting the enries with the unique IP addresses (192.168.1.22 and 192.168.1.23) since these are autodetected. Since these NICs are set up for NLB, there's no reason for the unique IP addresses to be 'seen' by the FVS318G.
I checked the documentation for the firewall, there's no reference to turning off autodetection of IP addresses.
Any suggstions?

As of now, there is no option to disable or turn off the auto-detection of IP addresses. However, you may post your concern in the Idea Exchange Board for Business here. Be reimnded that adding kudos to the ideas will help as development team will be reviewing the post that has the most kudos for considering it to add to the product's future functionality.
Let me also add that you may open an online case with NETGEAR Support regarding your concern. Your concern might possibly be escalated as feature request to the engineering team.
