If you have already brushed Merlin, you can try to use the suite ez-Internet that comes with Qunhui to automatically configure routing port forwarding and set ddns. If the port forwarding setting is unsuccessful, you can set it manually in the router management page-External Network-Port Forwarding.

If the white washing is successful, you should be able to access it directly with Qunhui's QuickConnect. All you need to do is enter quickconnect.cn/'s, your Qunhui Kuailian online, and you can use it. If you use a third-party ddns or a first-level domain name, you can set it in the external access -ddns in the control panel.
