Please share your output of : # pveversion -v # cat /etc/network/interfaces

100% packet loss when pinging google.com and proxmox.com is not what I would define as "DNS resolution works fine"....... From the PVE host what is the result of: # dig google.com # dig proxmox.com

Do you really need jumbo frames (mtu 9216) ? What is the result when you use standard MTU size, or delete the mtu lines in your config?

What does this command do on your PVE host: # ip link set enp10s0f0 up

You can try and use one of the two Intel nics. Maybe the Aquantia nic is not compatible with PVE8 and kernel 6.2.

From PVE host shell do: # pveam update # pveam available What template are you searching for?

You can ping indeed an ip address like 8.8.8.8, but you cannot ping 'google.com'. That's where DNS comes in, so please check that file like I mentioned here before.

https://en.wikipedia.org/wiki/Resolv.conf

please check this file: # /etc/resolv.conf It should contain at least one valid DNS server (like 8.8.8.8 etc) Or else add 192.168.68.1 as DNS server You can have max 3 DNS servers in this file.

From the PVE host what is the output of: # dig debian.org Also check on PVe host: # cat /etc/resolv.conf But like UdoB said, your Gateway is incorrect (or you have a very exotic network/Gateway config.....).

Thanks for your reply. I want to rename the Bridges into logical names that correspond with the nic naming. But I think I just leave it as it is...too much work and reconfiguration.

After you UNpin the 5.15 kernel and do a proxmox-boot-tool refresh, what is the output of # proxmox-boot-tool kernel list Maybe do a # apt reinstall pve-kernel-6.2

Sorry for asking, but what model/type NUC is this that has two onboard nics ? Google shows just this model with one nic...

Have you tried: # proxmox-boot-tool kernel unpin 5.15.30-2-pve # proxmox-boot-tool refresh

Hi, just a quick question: when I rename an existing vmbr0 to something like vmbr1 on the PVE host, all my vm's and lxc's loose their original vmbr0 connection. In other words, I have to re-assign in every virtual machine the new Bridge, because the old one is gone. Is there a fast way to...

Did you do a restart of the network service after changing the ip address? systemctl restart networking Or reboot the Proxmox server if you can.

Check your firewall/switch/VLAN config, because in theory you should not get a succesfull ping reply from other devices in (isolated) VLANs....

In the properties of the LXC, set IPv6 to static (with empty ip address) and not dhcp.

A quick Google search shows that more people with a Shelly dimmer cannot ping this device. Also, when I do a ping command from my PVE host (192.168.1.0/24) to any other vm in a VLAN, I get a time out. (I use OpenvSwitch - OVS). But again, isolating different subnets is the purpose of VLANs.

So now you have "bundled" all interfaces toegether (that's what a bond is)..... I believe a bond is a kind of failover, when one cable or port fails the other one takes over. Okay, if this works for you than that's fine. Not sure though if it is THE solution. Always nice when every...
