NATing blocking firewall

[fasi74]

I recently installed pfsense.

i require pfsense to allow all clients to access external dns servers for name resolution, however different clients should be sent to different DNS servers for that i have created rules in pfsense.
NAT is enabled and is automatic but the above rules arent working all the dns servers my guess is that nat is doing this

can anyone shed some light on this ?
