I have created a LXC container with Ubuntu 18.04 and added 2 network connections (1 LAN and 1 VLAN) both with the same settings for IPv4 DHCP and IPv6 SLAAC for the purpose of running avahi. At first it works and both connections show with ifconfig with IP addresses assign but communication through the Proxmox console eventually stops working and the container becomes unresponsive, cannot connect through console or ssh and cannot shutdown. Should I be able to have two network connections to a container or should I use a VM for this? If it should be working what can I do to diagnose?
