Strange problems resolving names

Here it was what I get on my computer directly connected to the dns. praise@praisenet:~> host irc.tin.it ;; connection timed out; no servers could be reached Strangely, if I try the same from a computer behind it, it works properly. I have tried to turn of my firewall, with no luck. I have also tried to disconnect and reconnect (I am using rp-pppoe) with nor esult. What else could I do? I am using Suse 8 Praise
