NAME

       firehol-client - client command

SYNOPSIS

       { client | client46 } service action [rule-params]

       client4 service action [rule-params]

       client6 service action [rule-params]

DESCRIPTION

       The  client  subcommand  defines  a  client  of  a service on an interface or router.  Any
       rule-params given to a parent interface or router are inherited by  the  client,  but  are
       reversed.

       For  FireHOL  a  client  is the source of a request.  Even though this is more complex for
       some multi-socket services, to FireHOL a client always initiates the connection.

       The service parameter is one of the  supported  service  names  from  firehol-services(5).
       Multiple services may be specified, space delimited in quotes.

       The action can be any of the actions listed in firehol-actions(5).

       The  rule-params  define  a set of rule parameters to further restrict the traffic that is
       matched to this service.  See firehol-params(5) for more details.

              Note

              Writing client4 is equivalent to writing ipv4 client and ensures this subcommand is
              applied only in the IPv4 firewall rules.

              Writing client6 is equivalent to writing ipv6 client and ensures this subcommand is
              applied only in the IPv6 firewall rules.

              Writing client46 is equivalent to writing both client and ensures  this  subcommand
              is  applied  in both the IPv4 and IPv6 firewall rules; it cannot be used as part an
              interface or router that is IPv4 or IPv6 only.

              The default client inherits its behaviour from the enclosing interface or router.

EXAMPLES

              client smtp accept

              client "smtp pop3" accept

              client smtp accept src 192.0.2.1

              client smtp accept log "mail packet" src 192.0.2.1
