無法從執行 docker 的 Proxmox 虛擬機器 ping 另一個 VLAN

無法從執行 docker 的 Proxmox 虛擬機器 ping 另一個 VLAN

我在從執行 Ubuntu 的 Proxmox 虛擬機器與不同 VLAN 上的 NSA 通訊時遇到問題。此問題僅發生在該特定虛擬機器上。我在同一台機器上還有其他虛擬機,可以很好地 ping 通其他 VLN。我注意到一件奇怪的事情是,當我嘗試 ping NAS 時,「寄件者」IP 位址不正確:

PING 192.168.30.17 (192.168.30.17) 56(84) bytes of data.
From 192.168.16.1 icmp_seq=1 Destination Host Unreachable
From 192.168.16.1 icmp_seq=2 Destination Host Unreachable

192.168.16.1不是虛擬機器的IP。這是我的 ifconfig:

正如您所看到的,我在此虛擬機上運行 docker,因此還有許多其他接口,包括 192.168.16.1。為什麼該介面在那裡,為什麼要使用它來 ping NAS?

答案1

事實證明 docker compose 正在創建糟糕的網路。我不知道為什麼或如何開始這樣做,但刪除它後一切又恢復了。
