Apologies—this topic relates to networking, but specifically within the Windows 11 OS. I know many people also use Windows 11 in a VM, so perhaps you can offer some advice.
This is my configuration for QM (on Proxmox VE 9.1.2)
I have a simple 192.168.100.0/24 network. A Windows VM is running at IP address 192.168.100.8 (there is also a WireGuard network, 10.10.8.10).I have had this Windows 11 OS installed for several months and have been checking whether it functions correctly.When I start the VM, the network works as expected. I can ping the internet, the LAN (192.168.100.0/24), and the WireGuard network (10.10.8.0/24).After some time, only the internet remains accessible; I can no longer ping the 192.168.100.0/24 or 10.10.8.0/24 networks.Sometimes this happens 1–2 days after rebooting the VM, while at other times, the LAN and WireGuard connections continue to work for up to two weeks after a reboot.I suspect the issue lies somewhere within the Windows settings, even though it is a clean installation of Windows 11 Pro 25H2.
I performed the installation following this guide.
