BR500 Port Forwarding Delays & 'vpn enabled' Messages

Just an FYI to anyone else who experiences any of this: I have disconnected my BR500 from the Insight service, rebooted the router, and the VPN messages have stopped (obviously!), the "NAT loopback" is allowing my LAN to reliably take advantage of port forwarding (sub-second connection again, before was either hanging or taking 10+ seconds to connect), and my router has stopped randomly rebooting itself.  Also, I am no longer seeing the sporadic high-CPU (sporadically 30 - 60+ percent) on the BR500.

Of course I no longer have any VPN (as ports 12973 (TUN) and 12974 (TAP) hang, even when the Open VPN service is enabled, which is the only reason why I enabled Insight + Instant VPN).  But having a stable, reliable, working router is much more important to me.

Another user on this forum shared that Netgear had suggested disconnecting from Insight as a possible solution to the random reboots, which is why I am sharing this, in the hope that it may help others.

No promises, your milage may vary, void where prohibited by law, etc., but for anyone who is at their wits end and frustrated with the BR500, as I was, this maybe a possible solution to regain stability if you can live without the Insight service.
