No connectivity after changing default TARGET

[Jorge Fábregas]

Hi,

I'm running 0.3.9.1 (Fedora 20) with the default "public" zone.  I'm
not
running any special rules (riched rules).  The only customization I did
to the default zone is to remove "mdns" and two or three more services
that come enabled out of the box.

Now, when I use firewall-config to modify the public zone:

- switch to permanent
- change the default target to DROP
- perform a firewalld reload

...I loose all connectivity. When I run "iptables -v -L -n" I see all
counters showing 0 packets/bytes.  I do notice the DROP lines in their
respective *public" chains (as it should after the change).  That is, if
you take a look at the iptables rules they all make sense (they should
work) but somehow, after changing the default target to DROP, it seems
packet aren't reaching netfilter at all.

Thanks,
Jorge
