nested=1 works, I also have this issue so feels like it's common. That shouldn't be the proper fix though, something wrong with Proxmox that needs fixing here?

Did you ever find an answer to this? I see multiple threads on this but never a resolution. I have a Proxmox Host, pretty fresh install and it doesn't work on Linux Bridges but if I change to OpenVSwitch it works as expected. The catch with OpenVSwitch is I seem to have to force VLAN tagging to...

Yeah I don't get it, I fired up an old server which has 5.3 on it in the same network, hell I even tried putting it on the same cable in the same port and it works fine. So I honestly don't understand what the issue is with the other server but seems Openvswitch gets around the issue. I'll...

I think I've solved it but only by working around it and switching to OpenVSwitch from Linux Bridges. It seems to work OK with OpenVSwitch.

OK rebooted the server, no VM's or containers starting on bootup. Switching on a single QEMU based VM running Windows. Ping it and all good. Turn on the firewall on the Datacentre and there's no firewall enabled on this VM and ping stops working. Switch Datacentre back off and it works again...

OK so installed PVE 6 and switched the firewall on straight away. All seems good on a clean install. Then restored a few VM's and Containers and then it's broken as it was on PVE 5. I believe it's one of the following that might be causing it but not sure which. Will try a reboot later after...

H Fabian, Sorry for the delay. I’ve had another look into this and it’s not across the board. I’ve noticed that it seems when crossing a VLAN it stays working. So an example. Laptop -> VM on same VLAN = No connectivity Laptop -> OPNsense Firewall (Virtual on Proxmox but with 2 x PCI...

Yes absolutely. Thanks for your help on this Fabian by the way. VM 200 - Windows Server 2019 Core Domain Controller but it affects them all or at least I tested a few and all the same. agent: 1 balloon: 768 bootdisk: scsi0 cores: 1 cpu: host,flags=+pcid;+spec-ctrl memory: 2048 name: kt-dc-01...

Hi Fabian, No problems at all. This is a long post but hopefully has the info you need but let me know if you need me to try anything else. I will of course wipe this server and reload it with v6.0 when that comes out but suspect this might be an issue there so hopefully solving that now...

This sounds very much like the issue I and another have. It appears the firewall is broken in the latest versions as it used to work fine for me.

As an update but made a new VM recently and see that the Firewall is ticked on by default on the VM NIC. Even with the Datacentre firewall setting switched off this breaks all connectivity to the VM until I switch the firewall off. Is it just lots of people don’t use the firewall or something...

Ah I don’t have to reboot in my case. Switching it off brings the connectivity back. I’ve of course got a firewall across VLAN’s but I liked that I could firewall inside subnet so one machine in a DMZ couldn’t communicate with another unless I allowed it. The firewall cannot help me there as...

Hi all, I've had the firewall working previously on a different host however on a new install recently I'm having problems with it and at a bit of a loss as to what the issue is. If I turn the firewall on in the Datacentre all communication with KVM and LXC machines running on the host just...

Just thought I'd say this is one of your best releases for a while with the LXC nesting allowing docker inside containers. Absolutely top work Proxmox team, please keep it up :)

I don't think you can fix this. Older versions of Proxmox were better but that's only because you could easier configure them to lie about commits to disk. You could likely achieve the same on Proxmox 5 by just setting your KVM VM caching to Unsafe. Just be aware if you have a power cut or crash...
