Why not try xinetd with a simple firewall rule?  I believe most people  
use xinetd or inetd and thus you should be able to get the most help  
that way.  I set it up the same way the documentation states. http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf 
   Have you successfully installed NRPE before?  If not, it may be  
time to move to a testing environment that you can have full control  
over.

That being said... Are you running SElinux?  Have you checked out your  
relevant logs for nrpe, iptables, selinux, etc (/var/log/messages,  
make sure debugging is turned on with NRPE)...  It may be give you  
some interesting information.  I like to run tail on the problem  
server then try NRPE from the monitoring server to see what is going on.


# REMOTE SERVER running NRPE daemon continuosly running tail
$ tail -f /var/log/messages
Sep  4 09:35:03 dev2 nrpe[7118]: INFO: SSL/TLS initialized. All  
network traffic will be encrypted.
Sep  4 09:35:03 dev2 xinetd[32709]: EXIT: nrpe status=0 pid=7118  
duration=2(sec)
...


# NAGIOS SERVER running 'check_nrpe -H REMOTEHOST' or have nagios run  
checks till they start to timeout.
$ ./check_npre -H REMOTEHOST
NRPE v2.11


Good luck!
