StrongSwanを使用するsite2site VPNトンネルがあります。すべてがうまくいくようです。ただし、最後に接続した人だけがアクセスできるという点だけが異なります。つまり、PC1から接続すると他のサーバーにpingを送信でき、PC2から接続するとPC1がタイムアウトし、PC2でpingを実行でき、PC2から切断するとPC1で再度pingできます。
そして
ipsec statusall
両方の接続でパケットが受信されていますが、そのうちの1つにのみ返されることがわかります。トンネルを通過するすべてのパケットに応答があるため、ルーティングの問題かどうかを確認します（サーバーはトンネルを介して接続された最後の人だけをルーティングします）。私はこれらすべてに慣れていないので、非常に基本的なものを見落としている可能性が高いです。
