Interfaces and firewall rules all look fine to me.  You can

Wherever the packets are going, but I'd expect them to end up on
virbr0.

Some other things to check:

$ cat /proc/sys/net/ipv4/ip_forward 
1

$ grep bridge /etc/sysctl.conf
# Disable netfilter on bridges.
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0

(Not sure if this is necessary, but see:
https://bugzilla.redhat.com/show_bug.cgi?id=512206 )
