normal Cox DNS which worked with a normal router. Installed Dell Sonicwall

Hi I am curious to why after installing a Dell Sonic-wall, the normal Cox DNS which worked with a normal router now doesn't and I have to use a google primary and secondary DNS on all the workstations?

With some home routers you can set the router as the DNS address for DHCP clients and it will forward onto the DNS server defined in the wan settings. No so for a sonicwall, you have to config DHCP to tell clients to use the DNS server you want.

Personally I use OpenDNS or google DNS servers, ISP DNS servers have caused me problems in the past.

Sonicwalls don't forward DNS queries by default.
