UPDATE:
I tried with FreeBSD8 as well and the DNS query didn't work. This is beginning to look more and more like an issue with my UTStarcom WA3002G4 ADSL2+ Router and its NAT config or the lack of it.
My setup and the ip addresses:
Router 192.168.1.1
Windows 192.168.1.2
Centos 5.4 192.168.1.3
FreeBSD8 192.168.1.4
The windows host works fine with no issues with DNS queries.
Best Regards,
Gaurav
