The "fw unloadlocal" command prevents all traffic from passing through the Security Gateway (ClusterClosed Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing. Member), because it disables the IP ForwardingClosed Process of transferring of an incoming traffic from one Cluster Member to another Cluster Member for processing. There are two types of forwarding the incoming traffic between Cluster Members - Packet forwarding and Chain forwarding. For more information, see "Forwarding Layer in Cluster" and "ARP Forwarding". in the Linux kernel on the Security Gateway (Cluster Member).

  2. The "fw unloadlocal" command removes all policies from the Security Gateway (Cluster Member). This means that the Security Gateway (Cluster Member) accepts all incoming connections destined to all activeClosed State of a Cluster Member that is fully operational: (1) In ClusterXL, this applies to the state of the Security Gateway component (2) In 3rd-party / OPSEC cluster, this applies to the state of the cluster State Synchronization mechanism. interfaces without any filtering or protection enabled.

Notes

  • If it is necessary to remove the current policy, but keep the Security Gateway (Cluster Member) protected, then run the comp_init_policy command on the Security Gateway (Cluster Member).

  • To load the policies on the Security Gateway (Cluster Member), run one of these commands on the Security Gateway (Cluster Member), or reboot:

  • See the related command fwm unload.
