## Symptoms

- * Continuous kernel log entries (log flooding), for example in *$FWDIR/log/fwk.elg* or in */var/log/messages* :  
  `cphwd_create_template: cphwd_set_seczone_out_ifn failed`.

* In some environments, SecureXL connection templates are not created for the affected traffic flows.

## Cause

This behavior can occur when all of these conditions are true:

1. The traffic matches an Access Control rule that is located below a rule that uses a **Security Zone** object.
2. A NAT rule uses **Security Zones** in its decision.

In this scenario, during SecureXL template creation for some connections, the gateway may not yet have the required outgoing NAT interface value available. As a result, the gateway can treat the template-creation state as an error for the affected flows.
