ping failure

I am having some struggles with my proxmox host and networking. Recently set-up opnsense on my proxmox host and everything is working fine. However when I try to ping google.com from my proxmox host I get 90% packet loss. I can ping 1.1.1.1 or my gateway just fine. Every LXC and VM running...

I am horrible about asking for advise and even worse at documenting what steps I have taken to try and solve problems. I just installed Proxmox 8.2.7 on a 6 node cluster. Every single things appears to be working fine. I can access GUI and SSH. Evry node can resolve addresses and I am able to...

Hello, I have a real problem for which I cannot find any solution. I would like to point out that I am a novice and that this is the first time that I have dealt with the concepts of LXC containers with proxmox. I specify that my container has an Ubuntu 22.0.4 template and that the major...

Hi everyone, thank you for your further help ... and, just in case, sorry for my english ... My lab test : PC1 : Promox VE with Win11 VM PC2 : Proxmox VE with PBS VM I've done a backup on my win11 vm to my PC2, everything fine, then I've shutdown my PC1 and restored on PC2 my Win11 VM Now, my...

Hello, I have a strange problem. I have a cluster running in a datacenter (Hetzner), and I'm monitoring it with Checkmk. The Checkmk server is also running at Hetzner; previously, it was running on a private IP for 10 days. Since I migrated, I am no longer able to ping or access the node from...

I just had this happen to a 2nd node. This one while still setting it up, before joining cluster. I had this happen to a node I had & I tried a bunch of things but eventually ended up migrating everything off it & re-installing. I thought it had happened as a result of an in-place-upgrade to...

I'm making this enquiry on behalf of a friend but seeing as I got him in to this I feel kind of responsible! That said, I'm still an absolute novice so terminology will likely be well off. Please be gentle! So, he states that after initially configuring a couple of containers (for running...

Hello, I managed to install proxmos on my server but it seems like I can't connect to the internet, any update command fails, I've done some troubleshooting but everything seems to be fine, below you can see multiple commands I've tried. curl https://google.com ip a cat /etc/network/interfaces...

Hi, I have installed a proxmox server (let’s call it PVE1). I have three NICs inside, which and all are used for virtual bridges : - vmbr0 - 10.66.10.2/24 - the management network, that’s the one I access the admin page from (http://10.66.10.2:8006) - the gateway for vmbr0 is 10.66.10.1 -...

hi guys, I'm trying my hand at networking, but I've run into a problem where I can't ping a machine or the internet. What I have done myself so far (which could be the source of the problem): i have set up a netplan for my gateway server (sudo nano /etc/netplan/00-installer-config.yaml) I...

This issue may somehow be of my own doing but I'm going to ask because I can't work out why. I have a 2 node cluster, both notes use the same x.x.x.112/28 IPs. Node 1 is x.x.x.122 and node 2 is x.x.x.123 The issue I keep getting is sometimes the VMs from one node can't connect to VMs on the...

Hi, I've setted up two Proxmox Servers in my home lab, each one running in a distinct physical server, but can't ping each other, neither join the same cluster. Both PVE can: Ping the gateway (192.168.15.1); Ping outside ips (8.8.8.8) Ping other devices in lan; Receives pings from my own...

I have a pve 7.4-1 host and two win10 guest system, they both work well when the host is directly connected to my router. But when I add a unmanaged switch between the host and the router, all the guest system have network error while the host is still good to work. The guest system failed to...

Dear all, first, please apologize my ignorance regarding networks and firewalls, resp. inability to use the search function, as i am afraid, i found similar issue in the past, which i cannot find again. We have a PVE cluster, in which one of the nodes hosts a VM configured as a router with...

Hello everyone! Today I met a problem that gave me a headache. The PVE host cannot ping the gateway (and no internet), but the VMs can (have internet). There are three ethernet cards in the PVE, two of which work: enp23s0f0 (as eno1 in the map) and enp2s0 (as eno2 in the map). enp23s0f0 is...

Hello, when I plug a new M.2 in my Asrock Deskmini x300, proxmox boot normal. The Server gets the static IP, but webgui and ping doesn't reach the Server. When I disconnect the new Storage, Proxmox runs normal and Ping and webgui work. Someone an idea?

Hey everyone, Proxmox and Linux beginner here. I've messed with Linux, but I still consider myself a beginner. I'm coming from running ESXi for the last 10 years. Everything just worked on ESXi with VLANs. I'm trying to get the same thing going in Proxmox with VMs and Containers. First I had...
