# '''A quick note about replacing firewalld with iptables: ''I've found that disabling firewalld isn't always enough.'' ''' Certain processes and packages can re-enable firewalld automatically and without notice. When this happens, though firewalld and iptables are both set to start with the system, firewalld takes precedence. Iptables will never start up. This can cause problems for students, as firewalld can interfere with some of our labs and they assume firewalld is disabled at this point. I recommend we amend Lab 1 to instruct students to fully remove firewalld from their systems. I also recommend checking status of firewalld be part of your troubleshooting toolbox when helping students with strange issues. --Chris Johnson
