[Pdns-users] How to avoid to be redirected to ad by my ISP if NXDOMAIN?

[Gerhard Gaußling]

Hello,

I'm using powerdns since a long time on ubuntu/hardy amd64. 
My ISP changed his behaviour and now I get on NXDOMAIN an ad site with a 
search form. But I prefer to get the firefox error page.

How do I configure pdns or the recursor to avoid this behaviour?
