I recently switched from Dnews to Leafnode++ for my home nntp server (exactly 2 days ago). Today I got a note from someone telling me that my news server had been Hijacked. I inmediately did a "deny log any to any 119" and removed leafnode from inetd. Sure enough I saw in the logs minutes later a computer trying to connect to my news server. How can I secure my news server? I can't think of what rules to use with IPFW. Basically I want the server to be able to connect to external news servers, but only want my internal network to be able to read from it.
