## Symptoms

- * Traffic is dropped with "`fw_handle_first_packet Reason: sam filter block or reject;`" although no SAM rule exists in the policy.

* "`fw sam_policy get`" output does not display a rule that matches the drop.

* "`fw sam -v -D`" was run to delete SAM rules, but the drops still appears.

## Cause

A SAM rule may be defined as a UserDefined script, as described in '[sk110873: How to configure Security Gateway to detect and prevent port scan](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk110873&partition=Advanced&product=Security)'.
