まず初めにServerにログインし、ルーティング情報を確認し、

サーバからの10.0.0.254へのpingはdockerが自動で生成するbridgeに向けられていることを確認
また、10.0.0.1へのpingの応答があるのは内部のdocker bridgeが応答しているためで、実際のルータへの疎通を確認しているわけではないことを確認

実際にはデフォルトゲートウェイの172.16.0.254を経由して10.0.0.254へ疎通をしてほしいため、docker bridgeのIPアドレスの変更(https://qiita.com/tana6/items/0e2e0f8d14307c0cc970)を参考に`/etc/docker/daemon/`を変更し、
{
"bip": "172.17.0.1/16",
"fixed-cidr": "172.17.0.0/16"
}
docker bridgeのIPレンジを変更した。
systemctl restart docker
でdockerを再起動したあとdocker bridgeのipが変わっていること

10系へのルーティングがなくなって10.0.0.254へのpingはデフォルトゲートウェイを通ること
admin@ubuntu:~$ ip r

10.0.0.254へのpingが帰ってくること

後述するトポロジのネットワークがあります。 このネットワークでServerからRouterにpingを実行した際に、172.16.0.254からは応答がありましたが、10.0.0.254からは応答がありませんでした。 原因を突きとめ、問題を解決してください。
