network adapter

Hi everyone, I'm in the process of learning to test proxmox and I'm having a problem with the network cards. my scenario. I installed proxmox on (vmware worksation) and added two network cards. One card is to communicate with my lab without internet access 10.0.0.0/24 and the other network...

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...

Dear Community, I'm struggling with setting-up the VLAN Trunking to VMs. I'm running on Proxmox 8.1.3 with a cluster of 3 nodes (DELL Server) I've an Allied Telesis switch, with this config: interface port2.0.4 description "PVE-LAB-01 Trunk" switchport switchport mode trunk switchport...

I am trying to get my 10G NIC to show on the PVE. however I only have one, the onboard 1G connection. root@pve:~# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet...

Hi all, Here's a newbie question, Why do the web gui state a network device to be active when no cable is connected to the physical nic? nor is that network device intentionally used anywhere else in the setup as far as I know at least. :confused: The nic has had a cable in it but not for some...

Hey all, hate to do this cause I know that there is a constant stream of "my NIC isn't as fast as I thought it would be" posts, but what I'm seeing goes well beyond any sort of CPU overhead or packet size issues. I haven't been able to find a solution anywhere that works yet, so figured I'd take...

Good evening, I have set up a cluster in Proxmox and it works so far. My problem is that the network interfaces are not really working. As in many other Proxmox installations, I have configured the network interfaces as Linux bridges. Then I edited the /etc/network/interfaces file and it...

When I installed proxmox, I installed a 4 port network card for a pfsense virtual machine. i scrapped that and debridged the network card connections but when i remove the network card, proxmox won't connect to the network. The ethernet is connected to the motherboard. I have VM's set up and...

For a HA system with 3 nodes, is it a fair assessment that can both use CEPH and NAS storage would work in this setup? 1 10GB nic for Storage (VLAN 10) 2 Bonded 2.5GB nic for Web interface and VM usage 2 Bonded 1GB nic for cluster (VLAN 1) Rather than make this look like Pepe Silvia...

Hi Guys! Some of my VM lose their network connections on random time and when I check the issue, It leads to turning off and on the network interface to solve the problem. Proxmox Version are 7.4.3 and 8.0.4 on different networks. Any idea how to solve the issue?

I set a dns name with duck dns to my ip address and it worked fine a while them I could not got to the web ui anymore. I could not ssh to the server either. I accessed directly the server and I discover that my two network interfaces where missing and vmbr is still there but gave an error as...

Hi everyone, I've seen many with similar issues, but no resolution that I could apply (at least I wasn't able to). I have a test PC that was running fine with PVE7. After the upgrade to PVE8, the network connection would stop after a few hours after reboot. The screen shows loads of messages...

Hi I'm trying to use Proxmox with the debian bookworm cloud image and cloud-init. But when I start the vm it gets stuck on boot when it checks that it has a network connection Job systemd-networkd-wait-online.service/start running (#s / no limit) for about 2 minutes. It seems Debian bookworm...

Hi there, I've tried to do as much reading up as I could on this before posting. I got the main takeaway that for debian 12 the AX210 was included so some of the issues I read for earlier versions don't apply now. I've struggling to get the interface to work with similar messages from...

Hey all, I have a DL gen10 server that I installed an HPE dual 10Gb 560FLR-SFP+ Adapter into. I've found that it will not pass bond0/LACP communication. An Intel X520-T2 with the same interface bond0/LACP config connects without issue. The switch shows LACP is communicating/connected. Does...

I have a server with Proxmox operating system installed, and I have created a virtual Windows 10 machine on it. The server is equipped with a Mellanox dual-port network adapter, each port capable of speeds up to 25 Gbps. When assigning the network adapter to Windows, I chose the virtIO model...

So, here is the thing. I have a dual SFP+ NIC that works well. I also wanted to place a 2.5Gbe Quad card into my proxmox machine. I am simply trying to do a Linux bridge within proxmox. The card is seen but won't become active. I tried a dual 10Gbe card and it was seen and would become active...

I'm trying to use a network card on my server, I've tried some configurations but without success, would anyone have any guidance on this? -network card does not appear in IP link Proxmox: 7.4-3 I tried this and it didn't work: $modprobe -r ixgbe $modprobe ixgbe allow_unsupported_sft=1 $...

Hello Forum I have searched the forum for an answer for about a month now, but I am unable to find one, or a similar solution to my problem. Recently I made the decision to migrate to Proxmox as hypervisor after using VMware since 2012. It goes very well. I’ve got an LXC container running and...

Hi, I have additional ip on Hetzner, but I can't figure it out how to use it, all my attempts have failed. Below I have attached my most successful host and virtual machine config. From a virtual machine, I can ping 173.1.2.98, but that's all. Thank you. Main ip Hetzner info: Gateway...
