I am very confused with my DNS setup,

My config

DSL Modem
pfSense (gateway, DHCP, opendns servers default)
untangle (bridge)
switch
wireless and wired pcs

gateway 192.168.0.1
UT 192.168.0.243


Here is the problem

I can browse the web with wi-fi clients
I cannot browse the web with wired clients (Besides I can locally control them in any means ping, rd etc etc)

I changed wired clients' dns servers to untangle instead of pfsense voila! it works...

But how come with wireless laptops can browse web without such modification to dns server.

I am confused?? I want to to use my gateway as default dns server not untangle. I saw some options under advanced such as bypassing dns? or similar, how I can browse the net ot wired customers without such modification to dns server?

Thanks

attached the modified wired network that can browse the net, if I change the dns server back to 192.168.0.1 again no connectivity to internet.

and here is ipconfig on wired machine
