So i've been trying to configure VLAN's for PROXMOX and VM's but i just cant seem to get it to work. An important information is that i am using a Fortigate 40F to configure the VLAN's, Policys, etc. Although i think my firewall config should be good. I think theres something wrong with the...

I have an issue with two Proxmox hosts which are misbehaving when establishing connections with pretty much anything. My own applications, apt, curl, ping, you name it. Both on the host and within LXC containers, things keep attempting to connect via IPv6, even though no IPv6 service is...

I installed proxmox on a vm with ip range 10.200.10.0/24 and on this range there is 1 DHCP server, then I created a vm using proxmox with vmbr0 but it does not grant dhcp ip to my vm, how do I fix it? What is this error and its cause? i fixediface vmbr0 inet static to inet dhcp I can't access...

Hi, I'm experiencing a strange behaviour on my PVE cluster with an LXC container. Context: I have a PVE cluster running on baremetal with version 8.1.3 with SDN Networking in place. I created an LXC container (Ubuntu22.04) on one host and I'm trying to reach the cluster API using Proxmoxer...

I'm trying to set up a router in Proxmox, ultimately this router should be connected to a VPN, and all traffic from any container inside Proxmox to the internet should route through there. To simplify it, there is the host on vmbr0, some containers on vmbr1, and the router (10.10.100.250) on...

Hi, first I want to thank everyone who answers on this thread and assists me with my issue! GOAL Have SDN VNet's for communication between VMs on different compute nodes and access the internet through SNAT on the VNet. ISSUE VMs configured with a VNet can't access the internet ping 8.8.8.8...

Hello, I'm a regular vmware user migrating to proxmox :) I'm new to proxmox and I haven't found an article that could answer my question, but if it exists I'd be happy to be redirected to it :) So, I've just bought a dedicated server from a datacenter - OVH, installed a proxmox on it and...

Hello. I hope you are well. I am new to Proxmox. I am having trouble getting Proxmox to recognize tagged VLANs. I have used a server to install Proxmox VE 8.2. This server is directly connected to a switch. The interface is configured in trunking mode with the required VLANs. As an example, I...

Hello, I would like to know what the recommendations are for managing subnets in a cluster of several proxmox nodes. Let's imagine the following scenario: I have 2 Proxmox nodes clustered in the network (192.168.100.0/24): The IP of node 1 is 192.168.100.10 The IP of node 2 is...

I use the DHCP server in the OPNsense FW (23.x) It runs as VM on separate PVE Node [7.x.x] The new PVE Node [8.2.2] has two interfaces One interface ETH0 is used as PVE Management bridged by VMBR0 and has a static IP on the same network as the OPNsense FW (192.x.x.1/24) The other interface ETH1...

-after PVE Node reboot the script runs after one minute and checks the installed network interfaces -the script updates a work interfaces file with the network interface devices it finds -the script then copies the work interfaces file to /etc/network/interfaces which is backed-up first -the...

Hi everyone, I have a very strange issue that I can't figure out how to solve vmbr0 is the lan bridge, I have another port (2.5Gbit/s) on the router that I wanted to switch along with the main one (10Gbit/s), as you can see from the picture, so that I could connect the ubiquiti AP to that (as I...

Hallo liebe Community, ich habe eine Frage. Ich spiele ein wenig mit dem Gedanken, eine zweite externe IP-Adresse hinzuzufügen. Momentan ist meine Netzwerk-Konfiguration so aufgebaut, dass alles weitergeleitet wird, außer Port 22 und 8006. Meine Frage wäre: Wie gehe ich vor, oder wie baue ich...

hi, I'm really a noob here so excuse me if this is some really easy stuff but I cant figure it out. I've got a vm with my gpu, wifi and usb cards passed, so I use it as a desktop. my ethernet port isn't passed to anything cuz that's how I connect promos to my network. I want to unplug it, but...

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...

i have configured a NAT before between proxmox host and its nested vms: the nested vms form a k8s cluster (192.168.1.2, 192.168.1.3,192.168.1.4), it is been two month everything was working as expetec, i was able tp connect the nested vms from proxmox host using ssh. yesterday i have...

Hello there! Today I changed my container IP through web interface, and then did a reboot. Suddenly I got an error while starting the container: run_buffer: 322 Script exited with status 1 lxc_init: 844 Failed to run lxc.hook.pre-start for container "111" __lxc_start: 2027 Failed to initialize...

I may or may not have typed in some wrong stuff: IP-Adress for the server: 192.168.2.10/64 gateway (as well as the DNS server both equal to the "speedport" (telekom) router): 192.168.2.1 DHCP ranges between 30 and 230 so my static ip for the server shouldn't conflict with these... I don't...

Hi, I am trying to reach the following configuration: Proxmox able to reach internet through the WAN (vmbr0) (I have a ISP modem) on a NIC (enp10s0), but without exposing the GUI or SSH (for better security) An internal LAN (vmbr1) on another NIC (enp5s0), on which Proxmox exposes the SSH and...
