.SH NAME
.PP
firehol-group - group commands with common options
.SH SYNOPSIS
.PP
group with \f[I]rule-params\f[R]
.PP
group end
.SH DESCRIPTION
.PP
The \f[C]group\f[R] command allows you to group together multiple
\f[C]client\f[R] and \f[C]server\f[R] commands.
.PP
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.
.PP
Nested groups may be used.
.SH EXAMPLES
.PP
This:
.IP
.nf
\f[C]
interface any world
  client all accept
  server http accept

  # Provide these services to trusted hosts only
  server \[dq]ssh telnet\[dq] accept src \[dq]192.0.2.1 192.0.2.2\[dq]
\f[R]
.fi
.PP
can be replaced to produce a more efficient firewall by this:
.IP
.nf
\f[C]
interface any world
  client all accept
  server http accept

  # Provide these services to trusted hosts only
  group with src \[dq]192.0.2.1 192.0.2.2\[dq]
    server telnet accept
    server ssh accept
  group end
\f[R]
.fi
