Hi, you need to setup a DNS relay on the firewall to your ISP's DNS address.  Details can be found here: ftp://files.dlink.com.au/products/DFL-260/REV_A/SetupGuides/How_to_configure_DNS_Relay.pdf (http://ftp://files.dlink.com.au/products/DFL-260/REV_A/SetupGuides/How_to_configure_DNS_Relay.pdf)

Best of luck,
Derek

you have to try things like a ping from pc to the dfl lan ip, solve it and
after that ping from the pc to adsl modem ip  solve it and

after that a ping from pc to some known ip on the internet solve it and

after that nslookup to verify name resolution solve it and

after that a telnet to 80 port to some known web page, and

after that you have navigation ok

have a nice trouble shooting   8)

another option is

restore factory defaults and try the wizard

after that analyze the rules and objects created to better understanding

dont worry

we all go through it at first with these firewalls its a nice feature the rolling back config if there is no confirmation
