私はLinux初心者です（CentOS 7を使用しています）。 2つのネットワークカードを持つワークステーションがあります。それぞれが独自のWANを持つように構成しました。ただし、同時にアクセス（pingを使用）することはできません。
- 最初のWAN：172.16.0.1
- 2番目のWAN：10.101.0.10
詳細については、次の出力を確認してください。

IP 10.127.111.1はGW専用回線：172.16.0.1に接続されています。 2番目のネットワークカード（WAN：10.101.0.10）をオフにすると、10.127.111.1が再生されます。これら2枚のカードをどのように受け取ることができますか？
ありがとう:)
