Seems OK.  I've found through experience that limiting outgoing
connections will sometimes cause issues.  I suspect it is because the
applications are more flexible on ports than the rules allow for.

And the drop invalid runs into issues with timeout in the firewall.  If
a connection is up but inactive for over 60 seconds, the firewall drops
it, leading subsequent communication to be dropped.

Why are you using multiple destinations for the http and https rule
instead of having two different rules?

/etc/sysconfig/iptables

Make the firewall you want and then run iptables-save and it will be
stored there.
