Is there still an issue with Tomato Shibby DNS? I have setup a guest vlan (br1) and when I set different DNS servers for each vlan either using
dhcpmasq dhcp-option=brx,6,xxx.xxx.xxx.xxx
or using iptables
iptables -t nat -A PREROUTING -i br1 -p udp --dport 53 -j DNAT --to xxx.xxx.xxx.xxx
iptables -t nat -A PREROUTING -i br1 -p tcp --dport 53 -j DNAT --to xxx.xxx.xxx.xxx
the guest vlan passes lookups to the new dns servers but does not use any of the dnsmasq options such as bogus-nxdomain=...
