Symptoms

There is a virtual server with SNAT pool configured. And a global default SNAT also configured similar to SNAT pool configuration. Traffic that hits virtual and uses the virtual SNAT pool to translate the source address. The same traffic stats will be reflected in default global SNAT though the default SNAT is not being used.

Impact

SNAT pool stats are reflected in global SNAT stats.

Conditions

A virtual server has a SNAT configured. There is a global default SNAT configured similar to the configured SNAT pool.

Workaround

Configure the default SNAT in a different VLAN.

Fix Information

The system now releases the default SNAT from the virtual server if there is a SNAT configuration directly associated with the virtual server.
