## Symptoms

- Packets are forwarded to an incorrect interface when SecureXL is on.   

* The parameter `cphwd_routing_interval=0` resolves the issue.

<br />

## Cause

An incorrect match occurred between the connection and an entry in the routing cache.

Do not leave this parameter disabled, it might cause performance issue's **in large environments** when we have USFW's.  

This parameter is just a workaround and to fix the issue we need to debug it (action plan in internal comments)
