  1. Frage zur Netzwerk Konfiguration

  2. 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...
  3. [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`?
  4. 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.

  8. 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...
  9. 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
  10. Proxmox (host) adding NIC with pfSense (vm)... I am confused...

    Hi I've been running proxmox and pfsense virtualized for some months now and am relatively happy about it. The proxmox-server is headless so when I once in a while screw things up, I physically move it and lose all internet connectivity, then plugin HDMI and usb keyboard so I can see what is...
  11. 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...
  12. [SOLVED] Installing PMG in OVHCloud

    Not sure if anyone has come across this and if they have a way around it. I'm trying to test out PMG in an OVHCloud VPS. Its a Debian 11 KVM and everytime I add the Proxmox repository and install proxmox-mailgateway it knocks out the ethernet address. There are a couple of things that they're...
  13. 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...

  15. Network interfaces have 2 types of naming on default Server mobo

    Ok so I couldn't figure out the right way to google this and it is kinda maddening... Fresh install of 7.1, on a SuperMicro server with 4 eth ports and I have both EN and ETH interfaces. WHY?! No extra nic cards in the system so why am I seeing both? I have been having issues with the system...
