    Realtek 2.5Gbit network interface drivers?

    Hi, While investigating stability issues with my Proxmox installation, I have looked into the Realtek R8125B interface I use. It seems to use the wrong driver. My UniFi switch often “auto-negotiates“ the ethernet speed on the switch port to Fast Ethernet (10/100mbit) instead of 1 gigabit (max...

    Can't connect to the network after NIC change

    Hi everyone, I've been doodling around with Proxmox for a couple of months and, sadly, I've recently lost the onboard Ethernet port on the PC I'm using as a server, the same I used for the initial configuration. I have handy a USB to Ethernet adapter which is being detected via lsusb but I...

    [SOLVED] why does vmbr0 has an IP?

    Hi According to the documentation, Proxmox uses tap devices (layer-2 devices which accept Ethernet frames) along the virtual switch (Vmbr0). I am not understanding why vmbr0 has an IP address, what is it needed for? and what is it used for? The code below is taken from the documentation for the...

    Incompatible card?

    Hello! I upgraded the kernel to 6.1. After installing a PTR-FU network card (RTL8125B) my main network card stops linking once the kernal boots and it is not reachable by the network, however it has the same IP as before. Any idea what it could be? Do you know if PTR-FU (RTL8125B) is compatible...

    Recommended NICS to use in proxmox

    Good morning, I am looking for a network card to install to my proxmox server. After investigating, the realtek NICs give a lot of problems to install in proxmox, so I don't know what network cards I could install in my server. I currently have an AMD Ryzen 5 5600G processor, running...

    Direct LAN connection between NAS and Proxmox

    Hello everyone, I installed Proxmox on a MacPro 2013. Because logically no further hard disks fit into these and I didn't want to spend any more money on an external hard disk housing with Raid function. I took my Fujitsu Esprimo P7936 and plugged in all my hard drives and connected them to a...

    [SOLVED] Assign External IP to VM

    I have two NIC cards: one is connected to the internet, the other is connected to an internal network. I am able to administrate the Proxmox instance just fine from the internal IP/NIC. Is there a way to move the external IP from the host's external interface to a single VM on `vmbr0`?

    VMs do not seem to get IP from DHCP

    I just created two VMs and for some reason they don't seem to get IP assigned from the DHCP server. When I give them static IP it does work. I just go into Proxmox fyi. So there must've been something I missed configured or haven't configured at all. Thank you.

    10G XG-C100F slower upload problem.

    Hi, first off, sorry if this is in the wrong category. I am kinda new to Proxmox and Linux in general but find it really useful, so I started tinkering a bit. I have a Windows 10 (main workstation) and a "home server", an E5-2678V3 on a dual socket Chinese board. My server is running a TrueNAS...

    kernel parameter irqpoll blocks `atlantic` driven aquantia 10G NIC from working

    My build runs with an MSI 10G NIC powered by Aquantia AQC107 chip. Whenever I use irqpoll or acpi=off in kernel parameter, the NIC is brought down on startup and `ip link set dev enp5s0 up` cannot bring it up but gives the error of "Invalid arguments" Can't figure out why

    How can I use my secondary NIC and wire it to vmbr0 to expand my LAN?

    My room has only one RJ45 port in the wall which is taken up by the Proxmox server and I don't intend to add a switch to connect the other device to the LAN through network cable. The Proxmox server has a 10G NIC which connects to the router and runs behind the default network bridge vmbr0...

    Unable to bond FC interfaces

    I have two 25G fibre interfaces on each server. I want to bond these in active-backup mode. They are connected to different physical switches. There are additional 10G interfaces for users to access VMs and ProxMox itself so these are not part of the usage for the 25G interfaces. I plan to...
