Well that didn't last long. My fourth attempt to find a router that does everything I need has failed after barely a week.
It turns out that the Billion 6300wx does not support NAT loopback. That's a minor pain for my laptop since I can modify its hosts file or hardcode things like email clients but is a more serious pain for my mobile phone. Looks like I'm going to have to leave wifi disabled on that by default and only enable when actually needed :(
