Hi All, I have an incus cluster of 4 hosts and a dozen containers, all Ubuntu 24.04. All containers are on macvlan each with an with IP bound by the router. One container is an nginx ssl front end for other containers serving various web pages. I have UFW on all hosts and containers. I get a few network timeout and unresponsive pages sometimes, especially first thing in the morning. Wondering if I’m blocking something I shouldn’t be. I’ve opened ports 67 & 68 for DHCP and IGMP ports.
Is there anything else I need to unblock?
Could somebody share a good UFW status output?
Does UFW even do anything in a container? It never logs anything into /var/log/ufw.log
Also what about fail2ban, does that work in a container?
Any help much appreciated
