I've got two nodes running in a Confluence Datacenter that I'd like to run the system firewalls on for extra security. The problem is that when I turn on the firewall on the local system (RHEL8), Confluence cannot be reached. According to the documentation, the only ports required are ports 8090 and 8000, which I have configured. I've also tried adding 8443 but still no workie.
Does anyone have any advice on this? Thanks!
