I current have setup that two routers are hardwired together, and the Guest WiFi is on br1 while, the main connection is on br0 -- and br1 doesn't have any access to the private networks.
Modem - Router 1 -- Router 2 - Guest WiFi
As such:
# routing for guest wifi access and drop of local private network packets
# per: http://www.linksysinfo.org/index.php?threads/guest-networks-vlans-and-tomato.70653/
iptables -I INPUT -i br1 -j DROP
iptables -I INPUT -i br1 -p udp -m multiport...
