家宽没有公网 ipv4，使用 AWS 做代理（ipv4 to ipv6）。
一开始使用 nginx stream，发现 nginx 并不会优先使用 ipv6，如果存在多个 DNS 记录，nginx 会轮询。
如果是 https 协议，nginx 需要开启proxy_ssl_server_name，并设置proxy_ssl_name，例如：

server {
    listen 443 ssl http2;
    server_name www.example.com;
    
    # SSL配置
    ssl_certificate ;
    ssl_certificate_key;
    # 其他配置......

    location / {
        proxy_pass https://127.0.0.1:8080;
        proxy_ssl_server_name on;
        proxy_ssl_name www.example.com;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        # 其他配置......
    }
}
