You cannot connect directly do the web GUI, you have to log into the control hub (if you have access), go to devices, find your device, and then from there you can access the web GUI as long as you can route to it. Cisco doesn't allow users to know the admin password of devices they are managing.    that said - I just did this to one in my company, I don't see any option to customize the wallpaper, but perhaps I'm just not seeing it (haven't tried this before).  ...

Yes, you can have the core behind a double NAT - as long as the ports are opened out to the Edge with return traffic it will work. I haven't tried it with core/edge, but I've registered endpoints to VCSE behind 2-3 NAT's and never had a problem, so I'm quite sure it will work.  ... View more

When the DX first came out, it ran android software, and you could use the USB to access files on your laptop from the DX, but you are not running android if you're registered to Webex. About the only purpose for the DX80 USB ports is for a headset or using it to charge a device.    ... View more

My guess is your problem is because the content channel on an MXP uses H.263, not H.264, and only up to WXGA resolution, no HD.
