mac address

Hi everyone, I'm planning to set up MAC filtering for IPv4 traffic in my Proxmox live cluster and aim to use ebtables and ipset where necessary, but I would like to primarily rely on Proxmox's built-in GUI features for easier management. As I'm still learning Proxmox's firewall system and...

HI, I have a motherboard with 2 NICs on it. a 2.5gb and a 1gb. I have been using the 1gb as my primary NIC since I built the machine and due to the nature of my setup was using the 2.5gb as a way to pass a 2.5 connection between some of my VMs and my PC. I have switched my networking around and...

Moin zusammen, für ein Projekt habe ich einen Proxmox Server 8.x laufen. Neben dem regulären Netzwerk, habe ich für eine zweites Netzwerkfreigabe einer anderen Abteilung erhalten. Ziel ist es einzelne Dienste über eine pfsense FW zu Routen. Von meinem Proxmox-Server wurde eine explizite MAC...

When creating a VM I tried to use a manually assigned MAC, after booting the OS(Ubuntu) and running ip a the VM correctly has the manually assigned MAC. However when checking the DHCP-server the ip lease contains some random very long MAC like this one...

Hello! I'm quite aware that there may be a few threads that detail similar issues like the ones I am facing, however this seems to be slightly special, especially with OVH's strange networking. The following setup is given: Proxmox VE 8 Host on latest Version with all Updates installed. Said...

I'd like to Pre-generate the Mac Address for a tool I'm building. I'm currently using one for VMware (and VMware only allows specific MAC addresses) and wondering if Proxmox has something similar? Is there a Proxmox SPECIFIC Mac address generator? (i'm guessing there is a function in the...

Hi I recently noticed a problem, I use a Mellanox VF (Connectx-5 EN) and it seems like it changes MAC-adress for each boot. That's a problem since I use SLAAC to add IPv6 adresses. Here is a screenshot from the manual. I guess that I can't be the only one with this issue, is there some good way...

This isn't really a problem (or at least I hope so), I just want to understand proxmox better, but I didn't know where to ask this, and I didn't find any answers on the forum. I was just messing with the router settings when I noticed, that whenever I turn on my proxmox machine, I have 2 more...

Hey, Ich habe jetzt in den letzten tage so viele Beiträge gelesen und getestet aber noch bin ich nicht am ziel wie erwartet. So kommen wir mal zum Problem: Ich habe eine Haupt IP nenne wir die mal <1>.244 und habe mir jetzt eine einzelne Zusatz IP gekauft die wir <2>.253 nennen. Das Problem ist...

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...

Hello, I have been using PVE for several months and recently I had to change my motherboard, after replacing the motherboard of my server I have a defect when starting the promox distribution: [FAILED] Failed to start LSB: Personal Firewall :mad: In front of my server I use a netgate...

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)...
