私は、ゲームや NAS セットアップなどのさまざまな用途でポート転送を有効にするために、VPS に Wireguard を設定して VPN として使用しました。
今のところ、ポート 45000、56000、40000 を開きたいです。私は 27fiber VPS 上の Ubuntu 22.4 を使用しています。
以下は私が追加したUFWルールです

問題 私はこのツールを使いましたhttps://www.yougetsignal.com/tools/open-ports/開いているポートをチェックしましたが、ポートは閉じています。UFW の再起動も試しましたが、うまくいきませんでした。構成について助けてください。
