Duplicate IPs

Hi Priya,

As far as I know, most Nagios plugins will check over TCP connections
and not need to know about internal IP addresses, so you can use NAT
just fine. 

If you need to run some plugin that does care about internal IP
addresses, you can use gateway hosts running the NRPE daemon to run your
checks inside each network, and have those gateways polled by the master
server using check_nrpe; or use distributed monitoring, as Andreas
suggested.

Cheers, Chris.
