network config

Good morning everyone, I am running into some issues with my ProxMox lab environment. I have a 4 Nic server running a handful of vm's and 1 container for testing, and I cant ping into the VM's, and can only ping out to specific machines that are not on the host. I have the 4 nic's in the server...

I've purchased a dedicated server from a data center as well as 4 reserved IP addresses. I've been trying to make this work for 10 hours but for some reasons VM's I create on Proxmox can't connect to the Internet. I am trying to assign these IP addresses provided to me by the data center but...

Hi everyone, I recently moved and I eliminated a subnet on my pfsense firewall, my first proxmox server is now sitting on this network and I changed the IP address in the web configurator to match the new subnet. for some crazy reason my proxmox server can ping half of my subnet, but not the...

Hi everyone, I've just installed Proxmox on an old laptop without any particular expectation or need, just to fiddle with it. My problem is that the Ethernet connection doesn't work. I searched a bit on this forum and apparently it's something that happens frequently, but I tried all the...

Hi! I recently shut down my whole box (after admittedly too long of uptime) to remove a redundant graphics card. After booting the hypervisor again, it had hard drive full errors. I ran the following commands to hopefully make some space and be able to see the web-ui again; apt clean journalctl...

Hi, I've been struggling for 3 days and trying to set up the network in different ways, I don't know what to do anymore :( My VM (linux or windows) does not have internet or probably because Contabo does not allow access to other MAC addresses than the legacy server? Could I ask someone more...

This is my first post so please tell me if im not following the guidelines. I have only been using Proxmox for a few weeks but I am having some issues since a CPU swap occured. I swapped from a xeon 1155 socket cpu to a i5 2500k 1155 socket. I previously swapped the other way around because I...

I connect 2 LAN port to my server and config file /etc/network/interfaces like this. auto lo iface lo inet loopback iface eno8303 inet manual auto eno8403 iface eno8403 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.25.22/24 gateway 192.168.25.1...

I have experienced this issue before where adding/removing pcie devices would rename the nics and I would need to adjust in /etc/network/interfaces. I tried doing this again but this time it won’t work. I have attached pictures of my results when using the “ip a” command and my...

Hi, I have a 10Gig card with 2 NICs I created the Linux Bond using these 2 NICs and then created a Linux bridge on top of this bond as shown below: I am using this bond0 as a LAN in pfSense by creating the Linux Bridge (vmbr1). pfSense recognises this interface (vmbr1) as 10 gig as shown...

I recently installed proxmox and I'm trying to learn, I read some topics and also the documentation but I couldn't find the solution to my problem: I virtualized 3 servers (1 almalinux lxc, 1 windows, 1 almalinux kvm) but the network works only on the lxc server Vm config: root@node:~# qm...

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...

Hello, very green proxmox attempter here. When I do apt update it is very slow and there are some "temporary failures". I have no idea what to set my DNS to and I'm not able to ping 8.8.8.8. I'm currently able to ping anything in my local network. I appreciate your patience on this!
