mac address

I was messing with one of the nodes on my proxmox cluster and experimenting with putting the management interface/GUI on it's own VLAN, and in the process managed to completely kill the network connectivity on the node even after undoing all my changes. I'll try to explain in a series of steps...

Hello everyone I have a custom firewall rule for a few VMs that I can't enter in the GUI. The most elegant way would be to load it directly at startup by "post-up" in the /etc/network/interfaces file. The rule looks like this: ip6tables --insert tap181i0-IN -m mac ! --mac-source...

hi I'm new here is this normal? The mac address is the same between proxmox and lxc but in my network setting show a different mac address eth0@if56: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 12:62:2b:6d:9b:9a brd...

Hi everyone. I need to install a software license server vm which requires a MAC address to stay consistent. How can I use the same MAC address if I decide to reinstall this VM? Thanks! Newbie here!

Guten Abend, kurze Frage: Ich würde gerne die statische IP Adresse meines Proxmox Servers über den Router vergeben (DHCP -> statische Adresse über MAC-Adresse). Bisher habe ich die Adresse direkt auf dem Proxmox eingetragen. Ich habe zwar gefunden, wo ich die Adresse des Proxmox ändern kann -...

Hi! Please help.

Hi Proxmoxers, Running a few VMs and CTs on Proxmox 6.2-4 on a server with multiple NICs. NIC ports are assigned to Linux Bridges and then connected individually to a particular VM or CT via the hardware GUI. I have noticed that in pve (in shell when I run ifconfig), the MAC address assigned...

My network has some issues. When the network traffic increases, the network connections tend to be very slow even though it's an 10GB network. I'm not sure whether it's proxmox-related or not. Example: VMx = virtual machine x VHx = proxmox virtual host x VM1 = 192.168.0.51 (E2:A9:CC:75:79:AF)...

Greetings fellow Proxmox users and moderators. First I want to thank the Proxmox team and developers for creating an amazing product. I have been a Proxmox user for only about 2 years but a Linux admin for about 15 years. Regrettably I have not created a forum account until now, however I...

Stumbled across something interesting last week that took me a while to understand. I have a number of VMs that use PXE-boot to install Centos7. I serve custom kickstart files from a local tftp server. Part of the kickstart file has an %include section that points to a local http server by a...

Hello, I have Proxmox 6 Server with LXC Containers. If I added some network adapter to one container everything works fine, mac address is on default settings (auto). But no mac address will generate. In syslog I have this error message: systemd-udevd[22359]: link_config: autonegotiation is...

I had update proxmox to latest version just now. It occurs problem. When I reboot LXC, LXC's mac address will change automatic. It makes me impossible to bind static address.

Anyone successfully used the Ansible module of proxmox_kvm to get a MAC address of a VM for a PXE install? Here is the task code: - name: Get Facts proxmox_kvm: api_user: "root@pam" api_password: test api_host: test node: test name: test validate_certs: no...

I have a server from hetzner, and install proxmox on it. My configuration is simple, and it's my "/etc/network/interfaces" file: auto lo iface lo inet loopback iface enp6s0 inet manual auto vmbr0 iface vmbr0 inet static address XX.YY.ZZ.TT netmask 255.255.0.0 gateway...

Ì'm having some issues with macspoofing on Proxmox as my CARP Master/Backup VIP's are flapping in state between the servers and stay that way they are set. I have checked: Disable hardware checksum offload Disable hardware TCP segmentation offload Disable hardware large receive offload...

When a Virtual machine is cloned, Proxmox deals with the MAC address by assigning a new one so there is no conflict. However, when cloning a LXC (by backup and restore to a new container), this does not happen. It would be nice to have feature that provider either: 1. An option to...

Hi. I 've got some troubles with VM and CT haven't access to network. After figure out, i found the trouble. It was a MAC prefix trouble. In fact I typing '69' for making sure to do not have some hardware conflict. But it doesn't support i think. I replace it by a simple '00' and all works...

Hey guys! So here is our config A dedicated server at OVH. Ipv4: for the proxmox host (also has 1 ipv6) We also have /64 of ipv6. So OVH blocks NDP, and does not give any Mac address for ipv6. If we give an IPv4 for a container, we can use ipv6, since it will the ipv4 MAC address. We want...
