I am using updated F16-beta and having problems making changes to IP tables using systemctl. The iptables I will work temporarily but the changes will not survive a reboot. System-config-firewall no longer appears to work. The service command now forwards to systemctl. And systemctl has no save command, and if it has an alias for the old save command under /sbin/service, I have not been able to find it. Either I am missing something here, or this issue needs to be addressed before the release of F16.
