Does LXD or LXC need any open ports besides 8443 to talk to each other?

Starting to crankup the iptables on my new cluster, anything else needed besides 8443

thanks

Expert Guys this should be a simple yes or no answer. Presently it seems to be working fine with 8443 allow on my firewall. But could be missing something?

8443 is the only inbound port you need to open, outbound you’ll want 443 for access to the image servers. In a cluster, you may also need 53 (DNS on TCP/UDP) between you nodes.
