    Allow packet Allow packet.

    Note When a new custom IPS signature is added, the IPS engine is reconfigured without any interruption to service, provided there is enough RAM free for the reconfiguration to succeed. For XG firewalls with a low amount of free RAM available, the IPS engine will restart, causing a small disruption in service.

Add the signature to a policy rule.
