bind

I have Ubuntu 12.04 with BIND9, working just as a caching server (forwarding to 8.8.8.8).

When I use, for example, dig +norecurse @l.root-servers.net www.uniroma1.it, I obtain the following output

; <<>> DiG 9.8.1-P1 <<>> +norecurse @l.root-servers.net www.uniroma1.it

; (1 server found)

;; global options: +cmd

;; connection timed out; no servers could be reached

Using Wireshark I discovered that the outgoing queries are correct, but there aren't any incoming answers. Why?

P.S. Using simply dig www.uniroma1.it I obtain the correct answers.
