I think China block all Blockchian NODE.
Router with VPN -> DeeperNetwork -> simple router : It works fine and can connect to anywhere especially it can find out active node in every country.
Router without VPN -> DeeperNetwork -> simple router: It can't work. No other node can be found.
I think the main reason is that the blockchian node are blocked in everywhere. I think it need some more smart connection method to hack on this. Like some special nodes can route in level1. Otherwise, it seems DeeperNetwork will recognized the China IP and directly blocked DPN active method.
If someone have more information on this, or any other method can help on this. Please let me know.
