network configuration

Proxmox Team, Multiple Windows 11 VM's hosted on on top of PVE 8.4 backed of kernel version 6.8.12-9 have been experience horrendous receive-side network performance (ex.in the order of hundreds of kilobytes per second) regardless of the device type (Realtek, E1000, VirtIO, etc.) and CPU modes...

Hello everyone, I hope you are good, I am a Linux sysadmin, who are using Proxmox in DEV env after having used VMWare, and I came across this strange issue, which is having 3 Proxmox bare metal hypervisors running VMs and VM's can't connect to the internet but the hypervisors yes. I have the...

New to proxmox and networking here. I recently got everything installed/set up however one of my 2.5 gb ethernet ports, the 2x 10gb ports and i think the wifi all show as inactive. I've done some reading and i guess it comes down to an issue with the realtek RTL8125? I have connectivity on the...

Hey that's I hope you all guys are doing great I am just new to the proxmox. Just starting set up my first proxmox server. Server Pc is HP Elitedesk 800 G4 TWR I5 8500 32GB RAM 512gb ssd 1tb HDD My network setup is Main ISP router > Tenda 8 Port gegabit switch >>My work PC >>Proxmox PC The...

Seeing this warning when starting `system-networkd` in an unprivileged container: systemd-networkd[000]: Failed to increase receive buffer size for general netlink socket, ignoring: Operation not permitted This appears to be referring to the sysctl net.core.rmem_max property which, AFAICT, is...

Greetings Proxmoxians! I am on the cusp of building a new cluster with 3 Dell servers. Each server has two dual-port 25Gb/s NICs, for a total of 4 ports. From a high-level, I'm counting roughly 4 functions that the network needs to perform: Management access (SSH and web UI) to the hosts...

Hi All, I have had proxmox running for a while without issues on a dell optiplex 7070. recently the server has started playing up. I am running version 8.4.1. My Config: auto lo iface lo inet loopback iface eno1 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.1.22/24...

Howdy folks, I have deployed 2 PA VMs within proxmox. I want to play with routing between these 2 PA VMs. Currently, the PA VMs can't ping each other using dataplane interfaces but they can using management interfaces. This is not a routing issue but rather an issue of how to configure...

Proxmox provides us with ability to enter IP on the ethernet adapter. But while connecting that to a Linux Bridge it will complain that the ethernet adapter has IP settings. What is the use of setting IP directly on Proxmox adapter? I have generally seen IP being applied to the Linux bridge...

I recently needed to change the IP structure of my proxmox cluster. I broke the cluster and changed IPs. I have one system that has lost the vmbr0 interface which has completely caused the system to loose network access. I currently only have IPMI access. Here is info on the system: Proxmox...

Hello, I have an issue with the connection. Explanation: I installed Proxmox VE 8.3 and completed the initial setup (following the installation guide). The device rebooted and redirected me to http://192.168.x.x. The problem is that it takes a long time to load, but nothing happens — the...

I upgraded to a new server which has dual 2.5gbit NICs and I'm running VE 8.3.5. My router/firewall is a Unifi Dream Machine Pro and I recently switched to Zone networking. I'm looking to configure networking for this host as follows: The two NICs are bound together for load balancing Two...

Fresh install of Proxmox (version 8.3.5) on a Dell T620 with 256 GB of Memory on a 1TB SSD. Boot sequence is great and I am able to reach the Proxmox web GUI, but after some amount of time initially it was 30ish minutes now it seems to get to about 6-12 hrs then the ethernet connection is...

I recently upgraded my NIC to a 4 port 10GBE. after this nothing network related and I have looked at multiple other times this happened on the forums and none of them helped. I have uploaded photos of some of the things that I commonly see requested. All of my CT and VM are booting up but not...

I'm trying to get coolercontrold up on my PVE instance. When installed on host and initialized, logs output: IPv4 bind error: Could not bind to standard IPv4 loopback address on port 11987 Is there any sort of firewalling measure on PVE that could potentially cause this?

Strange question, and honestly not a big deal, but just got me wondering. When I do an nslookup or a ping -a xxx.xxx.xxx.xxx, my plex LXC doesn't return a hostname. My router shows its name as UNKNOWN (where other IPs would show a hostname), even though I've confirmed the hostname within the...

I had a question about installing ProxMox. I recently installed 8.3 on a Dell R620, that has four ethernet ports, two 10G SPF and two 10G RJ45. Only the first one is connected. For some reason, it chose an unused ethernet port so the installation stopped and asked me for IP, gateway, dns...

Hi, I have a proxmox host with the following network devices eno1 vmbr0 And multiple interfaces as per the VMs ( VMID ). Firewall is checked on the VMs, but no rules are active tapVMIDi0 fwbrVMIDi0 Now I have two questions, 1. If I need to check the tx/rx bytes of the whole host machine...

Hello, New to Proxmox, but have been using different flavors of linux, VMs, and networking gear for quite some time now. For some reason I cannot seem to get my Proxmox to connect to anything on my subnet. On the initial install, I set the IP to a static IP (10.86.1.100), which falls in line...

I am running a PVE cluster (3) on 6.8.12-4. I have a Dell R730XD, and 2 R630s. 2 boxes have the Intel(R) 10GbE 4P X710 rNDC, and the other has the BRCM 10G/GbE 2+2P 57800 rNDC. iperf3 runs great between my NAS and PVE hosts (and their containers), but not on the VMs runnings on those hosts...
