really weird(?) DNS setup on linksys router running DD-WRT

[Marcelo Cavalcante]

Hi,
Why did you put  nameserver 127.0.0.1 in the /etc/resolv.conf?
127.0.0.1 is the localhost, just loopback. It means, you're trying to use
your own computer to resolve its names.
It's wrong. Try to remove it from the /etc/resolv.conf and test it.

cheers
