方案：使用Docker搭建，公网IP

Dockerfile

1.2.3.4：替换成公网IP

20010：替换成自定义端口

配置Tailscale

登录https://login.tailscale.com/admin/acls/file，配置Access controls，使用“JSON editor”，配置如下：

"derpMap": { "OmitDefaultRegions": true, "Regions": { "901": { "RegionID": 901, "RegionCode": "Myself", "RegionName": "Myself Derper", "Nodes": [ { "Name":"901a", "RegionID":901, "DERPPort":20010, "IPv4":"公网IP", "InsecureForTests": true, }, ], }, }, },
