私は数日間これを実行しようと試みてきましたが、今のところうまくいきません。私の状況は、SSID #2 の VPN (OpenWRT)ただし、若干異なります。
私の場合、OpenVPN を使用しています。2.4GHz と 5GHz 用に別々の SSID があり、5GHz には OpenVPN を経由する別のインスタンスがあります。
私が理解しているのは、IP ルーティングを確認する必要があるということですが、ネットワークに関する私の知識はこれを実現するにはあまりにも限られています。
私は「通常の」インスタンスを IP 範囲 192.168.1.x で実行しています。VPN を通過するインスタンスは 192.168.55.x にあります。
私が試した比較質問の答えについて
ip route add 192.168.55.0/24 dev tun0
しかし、次のようなエラーが発生します:
Cannot find device "tun0"
明らかに、tun0 は OpenVPN です。
文字通り、これをどう解決するか、どの方向に進むべきか全く分かりません。おそらく誰かがこれをやり遂げるのを手伝ってくれるでしょう。
編集：私は以下の手順を試しました特定のサブネットをVPNトンネルにルーティングするこれは OpenVPN 設定でも確認できますが、成功しません。
私の設定ファイル:
