OVH over VRACK LAN 上的场景 Proxmox 2.2

两个 VLAN 的两个桥接接口：

  • 5.135.XXX.XXX/26 网关 5.135.XXX.126 网络掩码 255.255.255.192 这是 Vrack 上的第一个网络
  • 176.31.XXX.XXX/26 网关 176.31.XXX.254 网络掩码 255.255.255.192

手动配置的接口（不使用 Proxmox 的 Web 界面）

为两个 VLAN 工作，但有任何问题。

从主机 ping 到： - 5.135.XXX.126 不工作 - 176.31.XXX.254 不工作

使用两个 VLAN 中的任何一个将主机上的所有 VPS 都正常工作

这个问题的精确帮助。我在这个问题上花了很多时间却没有找到正确的输出。它有效，但不如预期。
