    Looking for a Proxmox Specific MAC Address generator (as opposed to having PVE autogenerate it for me)

    I'd like to Pre-generate the Mac Address for a tool I'm building. I'm currently using one for VMware (and VMware only allows specific MAC addresses) and wondering if Proxmox has something similar? Is there a Proxmox SPECIFIC Mac address generator? (i'm guessing there is a function in the...

    Loading custom iptables rule on startup with post-up fails

    Hello everyone I have a custom firewall rule for a few VMs that I can't enter in the GUI. The most elegant way would be to load it directly at startup by "post-up" in the /etc/network/interfaces file. The rule looks like this: ip6tables --insert tap181i0-IN -m mac ! --mac-source...

    My network has some issues. When the network traffic increases, the network connections tend to be very slow even though it's an 10GB network. I'm not sure whether it's proxmox-related or not. Example: VMx = virtual machine x VHx = proxmox virtual host x VM1 = (E2:A9:CC:75:79:AF)...
