156-585: Check Point Certified Troubleshooting Expert

Certain IPS protections inspect or alter every packet in a flow and therefore force the affected connections out of the SecureXL accelerated (fast) path and into F2F processing, which can significantly reduce gateway throughput. Check Point recommends using the IPS protections' exception mechanism to limit application of protections like Network Quota, Fingerprint Scrambling, and TTL Masking to only the traffic/scope that genuinely needs them, so that unrelated connections remain eligible for SecureXL acceleration instead of unnecessarily bypassing it.

fw ctl zdebug performs kernel debugging while presenting the debug output in real time. This detailed tracing raises CPU load and should be run with appropriate resource and maintenance considerations.

FW Monitor can be inserted by specifying a relative position number from the chain listing, a relative position alias, or an absolute chain position. The -p all option inserts it at all inbound and outbound positions. Check Point: fw monitor

Setting ids_assume_stress to 1 makes the IPS engine assume the gateway is under load. With Bypass Under Load enabled, IPS inspection is therefore bypassed continuously instead of only after CPU or memory usage exceeds 80%.

SecureXL records accelerated traffic connection state in cphwd_db, its primary connections database. Check Point documentation describes this table as being maintained by SecureXL for connection tracking.
