    My Windows workstation and my Proxmox server are connected via a wired LAN. I've always SSHed into my Proxmox VMs via hostname, but hostname resolution suddenly stopped working, and I can't figure out why. This began immediately after I physically moved my router. I had to disconnect all the...
  10. DHCP not working within LCX or VM with Linux Native Bridge
