Thank you for the great guide, and explanation of settings!
I am one of those strange people with Proxmox running OPNsense in a DC. I currently don't have the rack space, or the budget to get a dedicated device for OPNsense, but that is on the list of things to do. I have been having some intermittent issues with my VMs and will try this and see if it helps.
I do have one question however. When doing some research I ended up looking at Multiqueue, what that is and if it may help. Networking is admittedly my weakest aspect in computers (well networking other then layer 1, I do hardware all day), as I understand it when using VirtIO (same as vtnet correct?) it only supports one RX/TX so the guest can only receive or send 1 packet at a time (over simplified trying to keep it short and concise). Now with modern hardware NICs can essentially make a packet queue for each CPU core (or Vcore). Will setting a Multiqueue value in Proxmox have any benefit? if yes I would assume it should be set to the number of cores the OPNsense VM has?
Thank you again for the great guide!
