Rule Group

SmartDNS supports rule groups, which allow for filtering rules based on domain or client matching.

The relevant parameters are:

Parameter	Function
group-begin [group-name] [-inherit group-name]	Begin a rule group
group-end	End a rule group
group-match	Match conditions for rule group, can be set to domain or client IP
conf-file -group	Include files in the specified rule group, equivalent to group-begin, group-end

You can specify matching rules using group-match, including client IP: -client-ip cidr, and domain: -domain.

Matching Rule Groups by Domain or Client IP

# Rule begins, named as rule.
group-begin rule
# Set matching rules, as follows for matching IP, MAC or domain.
group-match -client-ip 192.168.1.1/24 -domain a.com
group-match -client-ip ip-set:clien-ip 
group-match -domain domain-set:domain-list
# Set related rules
address #
# Rule ends
group-end

Configuring Group Inheritance

By default, group-begin inherits the configuration of the current group. To inherit from a different group, use the -inherit option to specify the group to inherit from.

# By default, inherits the configuration of the current group
group-begin rule
group-end

# Set to none to not inherit any group, using the default configuration
group-begin rule -inherit none
group-end

# Inherit the configuration from a specified group
group-begin rule -inherit another-group
group-end

Including File Rule Groups

You can also include external files to handle rule groups, making it easier to maintain and manage.

The main file includes external files, and -group specifies the rule group name.

conf-file client.conf -group rule

Included rule files, specifying matching conditions

group-match -client-ip 192.168.1.1/24 -domain a.com
address #
