Add a warning box to the troubleshooting advice in the local deployment guide about firewall rules on Red Hat Enterprise Linux. See this forum thread for context.
After some time searching online this morning there are a lot of different ways to tweak the firewall rules with varying degrees of safety. The k3s documentation suggests simply disabling firewalld as a first step.
