Why not use passive checks?  I have a similar problem where my nagios box
is in the DMZ and therefore not allowed to open connections to the private
LAN.  So, I installed a second Nagios box, added nsca there, and send the
results from the LAN-->DMZ which is permitted under our security policy.

I set all the host checks on the DMZ nagios box to check_dummy and use the
check_freshness setting to make sure the passive results show up on the
DMZ nagios instance at least once an hour.

Works like a charm.

See in general Nagios documentation on Passive Service Checks and
Distributed Monitoring.
