NAME

firehol-group - group commands with common options

SYNOPSIS

group with rule-params

group end

DESCRIPTION

The group command allows you to group together multiple client and server commands.

Grouping commands with common options (see firehol-params(5)) allows the option values to be checked only once in the generated firewall rather than once per service, making it more efficient.

Nested groups may be used.

EXAMPLES

This:

interface any world
  client all accept
  server http accept

  # Provide these services to trusted hosts only
  server "ssh telnet" accept src "192.0.2.1 192.0.2.2"

can be replaced to produce a more efficient firewall by this:

interface any world
  client all accept
  server http accept

  # Provide these services to trusted hosts only
  group with src "192.0.2.1 192.0.2.2"
    server telnet accept
    server ssh accept
  group end
