[Pdns-users] Running pdns alongside pdns-recursor on the same host

[Oliver Kent]

Sure, no problem. Here is what you need to set:

allow-recursion= [subnets you want to allow to recurse, I think they are
comma seperate but it may be by space]
lazy-recursion=yes
recursor=127.0.0.1:54

That should be it.
