I have Private Internet Access as a VPN service, and I wanted to use that for my FireTV alone. So I have a second router in my LAN, which basically serves as a VPN filter for my FireTV. Everything else on my network goes through the first router. So it looks like this:

192.168.1.1 = main router
192.168.1.12 = my Macbook
192.168.1.111 = second (VPN) router's address on main network (I can connect to this from my Macbook and administer the VPN router)
10.0.0.1 = LAN address of VPN router
10.0.0.50 = FireTV IP address

So! My question is...how can I ADB connect to my FireTV from my Macbook using adbFire?
