Also great to bypass Netflix/Hulu/Disney geo or VPN restrictions. I run ZT on my travel Amazon firestick, connect to my home network, turn on use default gateway and all traffic goes via my home router.
Using a similar setup, a friend in Oz and I also share ZT networks, so either he or I can use them to watch content that is only available regionally. The traffic uses home IPs, so it won't get blocked or detected.
It just works.
