NRPE doesn't "send". In the standard configuration, Nagios runs
check_nrpe on the central server just as it runs check_http and anything
else; check_nrpe makes a connection to the nrpe-server on a remote
machine; that remote machine runs the check it's configured to run, and
reports the result back over the connection to the central server.

I have a configuration that goes a bit beyond this. Server A is running
Nagios; server B is directly accessible; server C is on a private
network behind server B. In this case, there are several extra checks
associated with server C that actually hit server B's NRPE instance,
then fall through a second NRPE call to server C.
