Lxc
LXC 容器，無 LAN - 網際網路訪問
我正在 openSuSE 42.1 主機上設置 LXC 容器。
主機具有完全的 Internet 訪問權限，但容器沒有。容器可以 ping 主機，但在 LAN 或 Internet 上什麼也不能。
我認為問題可能是如何在主機上配置網橋，但我不知道如何解決這個問題。
主機有 eth0 和 br0。br0 已分配靜態 IP 地址等。
在 YAST 中，預設 IPv4 網關為 192.168.2.1，設備為 br0
這是主機的網路詳細資訊

容器配置文件是：

謝謝
您配置了網橋，這意味著主機和容器在同一個子網上。因此容器應該使用與主機相同的網關，但您確實將主機的 IP 設置為預設網關。將其設置為 192.168.2.1
