Hey!
I'm currently trying to set up a LXC with Ubuntu on Proxmox on Windows 10 (via Hyper-V). I'm having the issue, that the LXC seemingly can't connect to the netowork.
My setup is the following:
Windows 10 with Hyper-V (IP: 192.168.178.21)
Proxmox is running on that Hyper-V (connected to the network via a Hyper-V virtual switch which is set to "External Network" and got the IP: 192.168.178.20)
Ubuntu is running as LXC on that Proxmox (IP: 192.168.178.50)
- I can ping my router from the Proxmox VM (.20)
- I can not ping my router from the Ubuntu LXC (.50)
- I can ping the Proxmox VM from other devices on the network
- I can not ping the Ubuntu LXC from other devices on the network
- I can ping the Hyper-V host (.21) from the Proxmox VM
- I can not ping the Hyper-V host (.21) from the Ubutnu LXC
The /etc/network/interfaces of the Proxmox VM contains:
The Ubuntu LXC doesn't have a /etc/network/interfaces file? Is that needed and maybe the issue?
Network view (form Proxmox GUI) of the LXC:
Network view (from Proxmox GUI) of the host itself:
ip a from the LXC returns:
ip r from the LXC returns:
Sadly I don't understand much about Linux networking and have no idea. In tutorials I watched, it seemed to be working out-of-the-box.
Sincerely
