It's probably an mDNS issue, and replies should normally be allowed by the
default "accept RELATED,ESTABLISHED" rule.
It might be helpful to see the output of "iptables -L -n -v".
With the firewall enabled, as root,

You'll normally only see those lines when you're running virtualization,
or a DNS server. They aren't necessary for mDNS, which uses a different
port entirely.
I suspect that you see them because you're running libvirt. If you use
"iptables -v", you would see that those rules only affect packets on the
virbr0 interface. They're not related to your non-virtualized applications
(or to mDNS in any case).
Also make sure avahi-daemon and dnsmasq are running.

If mDNS is working when the firewall is down, we can assume that
avahi-daemon is running. dnsmasq is not required for mDNS.
