Looks pretty good for IPv4. But I want to play at IPv6 and discovered a few gaps in the GUI. It should be able to do DHCPv6, but doesn't. It won't allow you to fix an IPv6 address for a LAN host like you can with IPv4. It took a lot of back-and-forth with Asus before they would admit it. It also isn't handing out unique local or global addresses even though it has the info neded to do so. You have to get down to the command line level for that, and then any changes to the GUI overwrite any changes you make.
