NTA + Watchguard = wrong snmp interface index.


I enabled netflow of a Watchguard, of a single interface (external) and I receive 4 different and erroneous SNMP indexes. any idea?

the NetFlow Receiver Service is receiving flow data from unmanaged interface with index '1' on ****** and it does not support SNMP.

the NetFlow Receiver Service is receiving flow data from unmanaged interface with index '2' on ****** and it does not support SNMP.

the NetFlow Receiver Service is receiving flow data from unmanaged interface with index '3' on ****** and it does not support SNMP.

the NetFlow Receiver Service is receiving flow data from unmanaged interface with index '65535' on ****** and it does not support SNMP
