In order to use XBOX ONE to access US NETFLIX regions you need Linux based routers like DD-WRT to set NAT rules to reroute all TCP and UDP 53 port traffic to our DNS.
iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to-destination xxx.xxx.xxx.xxx:53
iptables -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to-destination xxx.xxx.xxx.xxx:53
You need to change xxx.xxx.xxx.xxx to any of our DNS server closer to your physical location.
We know this may be complicated for regular users but this is the only solution at the moment only for xbox one devices.
All other devices can access Netflix from tagged accounts as long as their static ip routing is setup properly as instructed here : http://support.smartdnsproxy.com/customer/en/portal/articles/1528973-static-ip-routing-for-router-modem
Meantime all our services like Amazon Prime US, Hulu, ABC, BBC, TVPlayer, Zatto, Pandora, etc. are working properly and can be accessed from XBOX devices. Thank you!
