    Hi, I have more than 6 NICS in my server. Is there a possibility to create LINUX BOND for LACP at the installation stage or add it after the installation for vmbr0? I tried but it says the default gateway already exists on vmbr0. Any ideas on how to achieve this? Cheers,
  3. VLANs broke in PVE-7.2-5?

    I have a VLAN (VLAN2) that I recently setup to separate all my hosts that are accessible from outside my network from the internal hosts.

  9. [SOLVED] Webui unreachable after adding nvme drive

    I just went through this issue and thought I should share. This seems more like a motherboard issue than a proxmox/networking one but I'm pretty inexperienced w/ linux.
