Chapter 13: Managing NNTP and General TCP Services
For example, you have configured news.myisp.net as your primary news feed through
the gauntlet-admin interface. To add support for a secondary news feed from
news.bigu.edu (192.168.1.202) to your internal news machine news.yoyodyne.com
(10.0.1.3), use the following lines in your netperm-table file:
#adds support for additional feed from Big University
nntp-gw: port nntp 10.0.1.3 desthost 192.168.1.202 destport nntp
nntp-gw: port nntp 192.168.1.202 desthost 10.0.1.3 destport nntp
Configuring Your NNTP Proxy for Reading News
You may not wish to carry a full news feed for your organization. However, you still
want to allow your users to read news. For example, you need to allow users to directly
access news servers on untrusted networks.
To configure for reading news from servers on untrusted networks:
1.
Use the gauntlet administration tools to disable NNTP configuration for your
firewall. This configuration handles a single internal NNTP server connecting to a
single external NNTP server. Set both the internal and external NNTP servers to
none.
2. Modify the netperm-table to ensure that the inside policy permits the NNTP proxy:
policy-trusted:permit-proxy nntp-gw
3. Add a section to the NNTP section of your netperm-table that indicates the hosts
that are allowed to connect to the NNTP port:
#allow any inside host to connect to the nntp proxy
nntp-gw: port nntp 10.0.1.* -port nntp
4. Configure internal news readers to read and post news to the appropriate news
server on the untrusted network.
