firehol-client - client command
.SH SYNOPSIS
.PP
{ client | client46 } \f[I]service\f[R] \f[I]action\f[R]
[\f[I]rule-params\f[R]]
.PP
client4 \f[I]service\f[R] \f[I]action\f[R] [\f[I]rule-params\f[R]]
.PP
client6 \f[I]service\f[R] \f[I]action\f[R] [\f[I]rule-params\f[R]]
.SH DESCRIPTION
.PP
The \f[C]client\f[R] subcommand defines a client of a service on an
interface or router.
Any \f[I]rule-params\f[R] given to a parent interface or router are
inherited by the client, but are reversed.
.PP
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.
.PP
The \f[I]service\f[R] parameter is one of the supported service names
from firehol-services(5).
Multiple services may be specified, space delimited in quotes.
.PP
The \f[I]action\f[R] can be any of the actions listed in
firehol-actions(5).
.PP
The \f[I]rule-params\f[R] define a set of rule parameters to further
restrict the traffic that is matched to this service.
See firehol-params(5) for more details.

\f[B]Note\f[R]
.PP
Writing \f[C]client4\f[R] is equivalent to writing \f[C]ipv4 client\f[R]
and ensures this subcommand is applied only in the IPv4 firewall rules.
.PP
Writing \f[C]client6\f[R] is equivalent to writing \f[C]ipv6 client\f[R]
and ensures this subcommand is applied only in the IPv6 firewall rules.
.PP
Writing \f[C]client46\f[R] is equivalent to writing
\f[C]both client\f[R] 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.
.PP
The default \f[C]client\f[R] inherits its behaviour from the enclosing
interface or router.
