forward _internal index from deployment server

Hi, I have the following outputs.conf set in deployment server but the _internal index doesn't seem to be forwarded to the Indexer. What do I miss?

outputs.conf

[tcpout] autoLB=true
autoLBFrequency=30
blockOnCloning=true
compressed=false
connectionTimeout=20
disabled=false
dropClonedEventsOnQueueFull=5
dropEventsOnQueueFull=-1
forwardedindex.0.whitelist=.
forwardedindex.1.whitelist=_.
forwardedindex.2.whitelist=_audit
forwardedindex.filter.disable=false
heartbeatFrequency=30
indexAndForward=false
maxConnectionsPerIndexer=2
maxFailuresPerInterval=2
maxQueueSize=500KB
readTimeout=300
secsInFailureInterval=1
sendCookedData=true
server=165.36.15.217:9997,165.36.15.218:9997
useACK=false
writeTimeout=300

===============================

Please help.

Thanks.
