Intel 1520 manual Following table describes the tags you can use in a rule, Tag Description

The following table describes the tags you can use in a rule:

Tag	Description
hostname	Choose one of the following:
	❚ host name
	❚ host name:port
	❚ IP address
	❚ IP address:port
	❚ .block—Use .blockto block access to specific
	news groups.
group-wildmat	This tag must be a comma-separated list of group
	names and list files in wildmat format (use * as a
	wildcard). The list file options are: subscriptions,
	distributions, and distrib.pats.
	Do not use spaces in the list. Use the prefix “!” to
	indicate groups not included in the list. The list is
	processed in reverse order, so more specific
	restrictions should be placed later in the list.
	Examples:
	❚ *,!distrib.pats
	The previous example does not include any
	distrib.pats files, but does include all others.
	❚ *,!alt.*
	The previous example does not include any
	groups of the form alt.*, but does include all
	others.
	❚ talk.religion.*,!talk.religion.barney
	,subscriptions
	The previous example includes only subscriptions
	from all talk.religion.* groups but excludes
	talk.religion.barney.
priority	This tag tells the appliance how to treat the specified
	host and news groups. Use one of the following
	options:
	❚ <no priority tag>
	If you do not use a priority tag, the appliance
	caches articles from the specified news groups on
	demand. If you specify multiple groups (such as
	alt.*), the appliance maintains a group list and
	will poll the parent NNTP server regularly to check
	for changes in the group list.
