Lab2.2 time out errors when trying to ssh back into the nodes. Noticed firewall rules changed.
In exercise 2.2, after running the bash scripts to install kubernetes on both the master and worker nodes, and connecting them using the kubeadm join statement, I walked away from my computer for a bit. When I returned, and tried to ssh back into the master and worker nodes I'm getting a timeout error. When I checked the firewall rules I noticed the "lfclass" firewall rule I initially created where the "Direction of traffic": "ingress", "action on match": "allow") is missing! There are a bunch of new firewall rules, including one for ingress where "Protocols/Ports"="all" and "Action"="Deny"
What happened? Is this expected? How can I ssh into the nodes as I did previously?
