NNTP

Network News Transfer Protocol (NNTP) is used to transmit Usenet news
articles.

The best way to use NNTP is to set internal hosts to internal news servers,
and external hosts to news feeds. In most cases NNTP has to be enabled in
both directions. If you are running a public newsfeed, you must allow
NNTP connections from all external hosts. External hosts can be spoofed;
WatchGuard cannot verify that these packets were actually sent from the
correct location.

Configure WatchGuard to add the source IP address to the Blocked Sites
List whenever an incoming NNTP connection is denied. All of the usual
logging options can be used with NNTP.

Common Scenarios

Scenario 1

Description

There exists a “public” NNTP server on the optional network.

Icons in the Services Arena

An NNTP icon–Incoming Allow From Any To the server.

Scenario 2
