networking

Hi all! I recently installed proxmox on my server, and now I'm trying to get networking in order. The problem that I have, is that for a certain VLAN, the DHCP response from my DHCP server doesn't seem to end up in my VM. It does seem to reach proxmox, but there's nothing arriving in the VM...

I know this is a bit of a long-shot but maybe there are some others with similar use-cases. Right now Proxmox has integrated support for virtual-eth networking to containers and it works well. I really want to be able to add interfaces to a container for network devices other than Ethernet...

Hello, We have a Proxmox server setup in our datacenter with a local network configured for the host (Proxmox GUI) and we have a second VMBR setup named VMBR1 with a Linux BOND for failover to access our public IPS. Now I was wondering, how could we prevent that our CT/VMS can ping our local...

Hello Everyone, I'm sweating my bal*s off right now, i've been searching for a definitive and working answer for days but nothing seems to work. To start i use the onboard motherboard NIC as the main one, which is on 172.168.1.0/24 LAN, which is also working fine as intended. As a second NIC i...

Hi, let me describe my use case first. I have a remote physical server of around 20TB. I want to use it to host my web app which is currently in GKE. So I want to configure my physical server to host my web app, I'm planning to install a hypervisor (proxmox) on my server and host VMs. Doubts...

I am self-hosting Proxmox VE v7.4 and have a Windows 11 VM configured with a SPICE display and SPICE enhancements enabled. I've installed both spice-guest-tools and spice-webdavd on the VM to enable folder sharing and I can connect to the VM just fine using virt-viewer on my local network. I...

Hello, I'm encountering an issue with accessing the web interface of my Proxmox server. Here's my setup: I have a Dell R710 server running the latest version of Proxmox, and I recently installed pfSense as a VM on it. Currently, pfSense is the only VM running, and it is connected to the...

I recently got a 10G NIC (Intel X540-T2). The plan was to run one port directly to my workstation and the other directly to my Windows server. I configured each port to have their own Linux Bridge and static IP on a separate ip range from the rest of my home just for this 10G, computer to...

I had one Intel X550-T2 installed on my server and all VMs were running fine and I setup OPNSense and had it configured with the two ports from the X550 being LAN and the onboard ethernet being the WAN interface using bridges. However, for OPNSense to really replace my router, I needed more...

Hey All! Hope you're well. Hopefully you can help, as I'm stumped here. I have a pve running in my homelab with one node. I have a Synology router that has their DNS server package that I host at the gateway so everything that queries DNS goes there and then forwarded on if needed. Very easy...

I look for support and guidance around where I am going wrong in a PROXMOX environment that I am setting up. I have one server that is connected and working for the Test Environment. It is running on the 172.16.0.15/16 network. We have three more servers that we have set up in cluster. The...

I'm moving from Windows Hyper-V to Proxmox and was excited, but I'm noticing that the websites hosted by these VMs (running Ubuntu Jammy) are loading incredibly slow. So much so that often on the first page load, I get an error 522 from Cloudflare (the sites are proxied through them) and then if...

I have a 5-node cluster with LXC only. From time to time, some LXC loses connectivity. It's sporadic, sort of random even. But when it happens I am very lost at how to properly debug it to know the specific cause of it. This weekend happened again. Took the chance to upgrade the node from...

Hey everyone, For the past few days I've been trying to get the additional ip on my Hetzner box to work on my vm, but I haven't been very successful. The vm's internet connection just doesn't work, attempting to reach any outside ip results in the ping returning no feedback, even after ten...

I used the =9916e23271e8cf3207741acc7714efa2']latest iso for did a fresh install. I used the network setup options part of the installer with the following parameters: Address: 192.168.1.10/24 Gateway: 192.168.1.1 DNS: 192.168.1.1 I can connect to the web portal with 192.168.1.10:8006: The...

I have three Gigabit Ethernet NICs installed on my Proxmox VE Host. If I want to have load balancing and fault tolerance Do I configure the Proxmox VE like this OR do I need to use the Bond and attach it to the vmbr0 Bridge? And do I need to configure the LAGS on the Cisco Switch's...

It looks like the topic of port monitoring is a bit above my current level of understanding and I haven't been able to find a concrete guide to help set this up. I have Hyper-V enabled on my Windows host and Proxmox is installed as a VM in Hyper-V. Proxmox was able to get a DHCP assigned IP...

Hello, I'm new to this with virtualisation and networking so I'm sorry if this question has been answer already, since I'm not able to search for the correct post. I have a cluster of two pve nodes and I have a pfSense VM installed and configured on one of the nodes with a virtual network...

Hi, I am unable to access any of my vms outside the proxmox window. None of the vms have internet, and im guessing its to do with the vmbr0 confirguration as I had to add that back after changing the file (see below) but I have no clue what it should be so my vms ips work. Ideally I would not...

Hello! I am trying to set up a Kali Linux virtual in my home lab for use with a mirrored port, or multiple mirrored ports and wireshark. I used this video to set up proxmox and Kali Linux: https://youtu.be/_u8qTN3cCnQ My issue is that I have one ethernet port on my Laptop, and have another...
