 Frequently Asked Questions
 Does BDA support replacing firewalld with iptables?
 Is there any concern about updating iptables with "yum update iptables" if that is necessary to install the iptables-services with "yum install iptables-services" due to dependencies on the ol7_latest iptables?
 Are there any concerns switching to the OL7 firewalld on BDA 5.2/BDA 5.1 with OL7 even though default iptables rules exist in /etc/sysconfig/iptables?
 Are there any consideration for making additional custom rule changes?
