Was there a IPv6 problem?

[ikke]

I updated my (non-subscription) pve server some days ago and had a lot of trouble with IPv6. After upgrading today everthing is fine again. I guess there was a bug in the kernel (or other?) before.

Additional I saw some threads with IPv6 problems here recently.

pve-kernel-5.13.19-2-pve -> problems
pve-kernel-5.13.19-3-pve -> fine again


@ proxmox-support: Was there a problem with IPv6 that's fixed now? What happend?

I found the problem, but not the solution. After creating and/or removing some interfaces in the Server Network configuration site und "Apply Configuration" some IPv6 Connection from VMs starts to flapping. After restarting the entire Server everything was fine again.

So it happens when restarting the network (via Weggui).
