We have three "check_commands_nrpe.cfg" files in our Nagios2 setup:

check_commands_nrpe.cfg
check_commands_nrpe_5667.cfg
check_commands_nrpe_5668.cfg

They are identical listings of the check commands save that the port
numbers are different (5666,5667 and 5668 accordingly).

This means that when we define a host that is behind another host
(i.e. monitoring Servers on a LAN from a WAN Connection) we just
forward port 5667 on the public IP to port 5666 on the private IP and
it all works.

Having said all of that, we're moving to an OpenVPN-based solution for
any machines that are in the current setup to remove the reliance on a
single point of failure.
