    [SOLVED] Fresh Proxmox & pfSense+ install - Slow network speeds

    Hello all, I'm having a bit of a difficulty with the internet speeds on a fresh install of Proxmox and pfSense. I was using an HP EliteDesk 805 G6 with an AMD Ryzen 5 processor with had an Intel i225-V 2.5GbE Flex IO V2 NIC for WAN and a Realtek 8156/8156B 2.5GbE USB to Ethernet for LAN. It...

    Proxmox fluctuation in Network Speed via Iperf

    I got an issue since a while that the network connection speed drops on my Proxmox. (I check it with Iperf3) I have an 2.5 Gbit connection but sometimes the speed drops to 1 Gbit or sometimes even 100 Mbit. The clue is. I get this resolved 99% of the time when I change the MTU in the GUI from...

    Proxmox node works at 2.5GbE upstream but capped at 1GbE downstream

    When running iperf3 between devices on my LAN I am having an issue with my network throughput. I have a Beelink EQ12 with Intel i225v chipest and when connected to a 10GbE switch via SFP+ tranceiver I am able to get 2.5GbE throughput on the upstream to iperf3 servers but when going downstream it...

My Proxmox server is running on a Topton Intel 13th gen 8505 mini pc with 8x Intel I226-V nics and...

    Proxmox & OPNsense - 10% of the performance vs. Bare Metal, what did I do wrong?

    Hi all, having some problems which I hope I can resolve because I *REALLY* want to run Proxmox on this machine and not be stuck with just OPNsense running on bare metal as it's infinitely less useful like this. I have a super simple setup: 10gb port out on my ISP router and PPPoE credentials...

    Networking speed issues: 1Gb/s instead of 2.5Gb/s

    Hello everyone I have a 4 ports QNAP 2.5Gbits NIC that I passthrough my Opnsense VM and through that this VM is able to get an Internet speed of around 2.2/2.3Gbp/s so this is OK. On my Proxmox hypervisor i have another 2.5Gbp NIC that is used as a bridge for all LAN VMs. If i check with...

    Use USB NIC as main NIC in Proxmox?

    I attached a Plugable 2.5Gbe USB adapter to my Proxmox install, my goal is to assign it to VMs and get the higher throughput and also to use it for backups/restores to my NAS. They are attached to a 2.5Gbe switch. I can't seem to get the drivers working on Ubuntu, I installed the Realtek 2.5Gbe...

When i boot up the usb to install it, it fails with the No network interface found...
