What's the current status of AsusWRT and Merlin firmware in terms of supporting Full Cone NAT / Open NAT Filtration? I noticed in the feature overview that you mention; "Full cone NAT support (RT-AC86U only)" which sounds great. But what is the reason for this only being available on this specific model and not any of the others? And is this something you had to add yourself or is it supported by default by this model? Is this feature a simple toggle in the webui in order to choose between secure/strict nat filtration and open nat filtration?
