Part of the Furniture
Weird asus can't implement their own support for this, but Broadcom has alot invested in these routers.Most likely never. Fullcone support in kernel 4.1 was developed by Broadcom, and their patch is no longer part of the 4.19 kernel SDK due to changes to the Netfilter implementation that aren't compatible. So unless Broadcom decide to write a new patch for 4.19, it's not coming back.
