Your netgear router will probably sit right behind your modem. Behind your netgear router will probably be your LAN containing your TV's, computers and other stuff.
Connect the WAN1 port of the MX to a lan port behind the netgear router.
If you have all the necessary ports open on the netgear (by default they will be open) the MX will register with the cloud and form it's VPN tunnel to the hub.
Then you can add your company pc and devices behind the mx on those lan ports.
