IPv6 OFF. How?
I've been trying a few things at home on the Ultra 2+ and I've been looking to disable IPv6. I've tried the usual Google/Linux/Etch/Deb web guides... EXAMPLE # vi /etc/modprobe.d/aliases ...

I'm not sure what you meant by "disguising it's VPN address with a fake LAN address". 5.xxx.xxx.xxx is the termination VPN address (a bad choice on Netgear's part, but that's another subject).
The IPv6 assignment in Remote is a bit of a puzzle. Like the ipv4 address, it could be the termination of the tunnel (and only used by the NAS itself, not any devices on your network). In this scenario, the vpn tunnel is tunneling both IPv4 and IPv6. One rationale for this is that it would allow an IPv6 remote device to use the tunnel. It would do no harm, and wouldn't depend on your local LAN equipment supporting IPv6 - since the tunnel itself is opaque to your local LAN (all the traffic it is tunneling is encapsulated)
It could also be a bug - in which case the ipv6 address is not used, but does no harm.
Either way, there is no reason to be concerned. The remote addresses are purely local, none of your LAN equipment (including your router) ever sees them.
