Multi wan with multi DNS servers

[demonmaestro]

I have dual wans and I want my wan 2 to go to OpenDNS dns servers. I have changed the dns settings but when I go to test the dns servers it is still going to 8.8.8.8 on a computer that is designated to go to wan2

pfSense usually queries all the DNS servers simultaneously. If you have pfSense acting as a DNS forwarder (though dnsmasq or unbound), you cannot control in this way which server is queried depending on routing rules.
