I'm a security architect and I work from home when I'm not on the road.  I have my own PKI for my internal (home) network.  All I want to do is to change the default certificate used by the WebUI 'server' on the router from the built-in cert to one that I issue from my internal PKI.  I REALLY don't want to add the built-in cert to my browsers' trust stores if I can help it but this doesn't appear to be an option that I can find.  If so, this seems to be a tragic oversight for a high-end router.  This is the first time in quite some time that I've used a router that wasn't running DD-WRT, Tomato or some other similar OS.  I like most of what I've seen on this router (particularly the range even before meshing) and I'd like to stick with it but this seems like a 'duh' moment to me.
