The best way to get VPN up and running ( imho) is using internet form a Mobile Network provider, ideally thru a USB dongle. I have lived a while in China and using vpn on cabled connections was a gamble but using China Unicom sim card in a dongle worked like a charm always. I was using an AR300M GLiNet router and PureVpn or ExpressVpn ( depending which one was giving me a better speed in the location I wanted to get access to).
