the gateway is inspecting the traffic. Assuming acceleration is enable which path is handling the traffic?

The Slow Path is the processing route where traffic undergoes full Security Gateway inspection by the firewall kernel workers (F2F). When SecureXL is enabled, only traffic that matches existing acceleration templates bypasses inspection - new connections, complex rule matches, and traffic requiring deep inspection are not offloaded and remain on the Slow Path. The premise that the gateway is inspecting the traffic confirms it has not been accelerated, placing it definitively on the Slow Path.

Medium Path refers to traffic that is partially processed by SecureXL with limited firewall involvement - it does not represent the full gateway inspection that the question describes.

Fast Path means traffic is fully handled by SecureXL acceleration templates and completely bypasses the firewall inspection engine, which is the opposite of the active inspection described in the question.

Accelerated Path is synonymous with Fast Path in Check Point's SecureXL architecture - packets on this path skip Security Gateway inspection entirely, contradicting the scenario where the gateway is inspecting the traffic.
