I had turned off firewalld and was using iptables when I originally installed CentOS 7.0. Two days ago I upgraded my CentOS 7.0 to 7.1. Everything seemed to be fine. Today I discovered that my iptables configuration was removed with the update. Has anyone else experienced this on doing upgrade? Literally the /etc/sysconfig/iptables is gone and the /etc/sysconfig/iptables-config is the blank template that comes with the distribution. This seems to me to be a serious bug with the upgrade.
After the my mail server upgraded to 7.1 I have been unable to gain external access because of the firewall changes. I am working on trying to figure out what has happened. Looks like 7.1 has some bugs.
