I am playing with Proxmox in Azure. I set up a vanilla Debian 12 OS with two NICs. I was able to install Proxmox using This Guide and without much fuss. I can create and run both containers and VMs. The issue I am having is with networking, guest VMs and containers are unable to access even the local network. DHCP on guests does not result in an IP address and static configurations do not result in any connectivity. Guests can ping each other, but not the host and beyond. Does anyone have any suggestions or is there any further details I can provide? Below is the output of ip -a on the host

Bash:
