Hi,
I just had a fresh install of Proxmox VE 5.1 (see pveversion -v below) on a couple of R610 with PCI Intel NICs (one ixgbe and one quad-e1000). I tried to move a few VMs from a legacy Proxmox VE 4.x cluster to that new cluster, which is located on the same switch than the legacy one. Everything is working fine with IPv4, but it seems that IPv6 bridging is not working anymore.
I tcpdumped on the concerned vmbrXX within the hypervisor:
From/To the "outside world": It does not work (no IPv6 at all coming from outside, and the VMs tries to reach outside stuffs).
Between two VMs located within the same Proxmox hypervisor: It works (ping OK)
I didn't test between two VMs located on two different cluster members yet, as it seems that I also have a VM migration problem, but since it's not the issue here, I don't ask anything about it. Ifneedbe, I'll open another thread
It reminds me that old thread:
https://forum.proxmox.com/threads/ipv6-bridging-issue-with-latest-pve-kernel-3-10-0-7-pve.21048/
Is it possible that we have an old bug coming back with IPv6 bridging ?
If you need additional infos, let me know
