bridge only works with Windows

[Fredware]

Hi,

Proxmox 7.2.7 installed on debian 11

Network conf on host:

source /etc/network/interfaces.d/*


auto lo

iface lo inet loopback


auto enp5s0

#iface enp5s0 inet dhcp

iface enp5s0 inet manual


iface eno1 inet manual


auto bond0

iface bond0 inet manual

        bond-slaves enp5s0 eno1

        bond-miimon 100

        bond-mode balance-rr


auto vmbr0

iface vmbr0 inet dhcp

        bridge-ports bond0

        bridge-stp off

        bridge-fd 0

My Windows Server 2022 VM, works fine with Virtio network drivers on bond0
But when I tried to create CT or VM linux, not network connection.

CT with Ubuntu 22.04 cloud images
VM Freepbx not connected on install wizard.

Do I need install something else to get network on bridge bond0?

VirtIO driver isn't built-in kernel?

Thanks

Hi,
what does the configuration of on of your VMs look like (qm config [VMID]). What does the config within the container look like?

I tried with network card E1000 or RTL8139, same issue.
Thanks

How does Freepbx get its IP? Did you set one?

 

[Fredware]

Oh!
I thanks it was DHCP, but, when I set an IP choose from my lan range, it works!
How is it possible to not have DHCP working?
Thanks

 

[shrdlicka]

Did you activate the firewall in Proxmox?

 

[Fredware]

In Promox Node settings, Yes.
In VM, with or without firewall, no DHCP working.

 

[shrdlicka]

Could different things, you could try to monitor network traffic if you see a dhcp request. You could also try if this happens for a basic debian install.

 

[Fredware]

Strange thing, no dhcp request, on VM or on host.
Yes maybe install form debian basic is the problem, but I can't reinstall.
Thanks for your help and sorry for not solve issue.
