    [SOLVED] Vmbr0 bridge unknown device type - can't create interfaces, VMs or CTs

    Hi, I'm having an issue where I cannot add new interfaces to VMs, or even create new VMs, because proxmox lists my vmbr0 bridge type as 'unknown'. This means that I have no devices listed in the 'bridge' option box when creating interfaces or VMs, and therefore they cannot be created. I can...

    I've been at this for a week, and I can't figure it out. Sorry for the Information dump, but I'm hoping that someone can take a look at the below to both try and solve my problem, and also offer a sanity check that I'm properly using VLANS and routing in my network and within Proxmox itself...

    Is it safe to disable vmbr0?

    We run a proxmox installation and our networking setup is VMs go over NAT on vmbr1. We want to disable vmbr0 due to VMs accidentally being created on vmbr0, and us getting MAC spoofing abuse reports from our server hosting provider. There seems to be no traffic over vmbr0. root@pve:~ # cat...

    1 public IP, two bridges, port forwarding

    Hello Guys, currently running proxmox 7.2-3 on a dedicated server. I got only one public ip (eno1) and two bridges (vmbr0, vmbr1). The idea is to have some VM's over vmbr0 (more management like tooling) and some others over vmbr1. Does that even make sense to set it up that way? I tried to...

    [SOLVED] Stop Proxmox From Occupying an IP Address on vmbr0

    My ISP has given me two networks, one that's firewalled (vmbr1) and designed to be used for the Proxmox host along with development/testing VMs. And another non-firewalled network (vmbr0) that is supposed to be used for production VMs and its open to the internet with no firewall. Each of...

    LXC loses network interface after a few days - possible solution found, but why?

    Hi, I have installed a Turnkey-fileserver (LXC) to create SMB/CIFS and NFS-shares with low resources and fast disk I/O instead of having to create a VM (also because I've read it's a bad idea to install those things directly on the host). The problem is that after a few days, I usually cannot...
