我有一個連接 2 台伺服器的專用網路：
server 1: IP 10.0.0.2
server 2: IP 10.0.0.3
當伺服器 2 使用 VPN 時，我希望能夠使用伺服器 1 中的以下命令透過伺服器 1 連接到伺服器 2：
ssh 10.0.0.3
為此，我在伺服器 2 中建立了以下規則
ip rule add table 128 from 10.0.0.3
ip route add table 128 to 10.0.0.0/8 dev ens10
ip route add table 128 default via 10.0.0.1
從上面的程式碼來看，從伺服器 2 發出的請求應由表 128 處理，並透過網關 10.0.0.1 透過 esn10（專用網路介面）進行路由。
但問題是，當從伺服器1 ssh 到伺服器2時，沒有回應（即使沒有連接VPN）
應用上述規則後，我將“ip route show table all”命令輸出貼到此處
default via 10.0.0.1 dev ens10 table 128
10.0.0.0/8 dev ens10 table 128 scope link

這是 ifconfig 的輸出：
