# Method: firewallHelper
#
# All modules using any of the functions in FirewallHelper.pm
# should override this method to return the implementation
# of that interface.
#
# Returns:
#
# An object implementing EBox::FirewallHelper
sub firewallHelper
{
return undef;
}
# Method: usesPort
#
# This method is used by the firewall to find out if a given port
# is available or not. So if your module implements the
# EBox::FirewallHelper to allow some ports for the service it manages,
# you must implement this method to inform about this when requested.
# This means you should check if the requested port is used by your
# service.
#
# Parameters:
#
# protocol - protocol (tcp|udp)
# port - port number
# iface - interface
#
# Returns:
#
# boolean - if the given port is used
sub usesPort # (protocol, port, iface)
{
return undef;
