Trouble on VM Net Bridge

[corent1.csn]

Hello, I installed a Proxmox cluster of 3 servers about a week ago, which is fairly functional.

The networking setup is as follows:

• Port 10G n°1 (VM Access)
• Port 10G n°2 (CEPH) - Static IP = 172.30.10/24
• Eno3 (Proxmox Interface)

To connect my VMs, I have two bridge interfaces:

• vmbr0 (MGMT) = 192.168.30.31/24 --> Bridged with the Eno3 port
• vmbr1 (VM Access) = 192.168.30.10/24 --> Bridged with the 10G n°1 port

I am facing the following issue: my virtual machines are only accessible through vmbr0, but as soon as I change to vmbr1, the VMs are not even able to contact the bridge interface IP.

However, both bridge interfaces are accessible from any physical machine on the network.

Do you have any suggestions for troubleshooting this issue?

Thank you in advance.

Hello,
can you check if the Autostart for the VM network interface is checked?
