vmbr0: received packet on eno3 with own address as source address​



Best Regards,
 
Hi,

May you provide us with the network configuration `cat /etc/network/interfaces` and where you see the above message?
 
Hi,

Thank you for the outputs!

It looks like you have a loop on the NIC `eno3` which has received a packet with its own MAC address as the source address. I would check from the following in order to narrow down the issue:

- Check the network topology to ensure that there are no network loops.
- Verify that there are no IP conflicts in the network.
 
Hi.
I checked what you told me. But i foun that a Vm had the same MAC as the proxmox server i change the MAC and i dont have the error message.

Thank you very Much for your Help!!

Best Regards.
