Hi Marty, 

I don't see the specific ports on your iptables output.  In my 
/etc/sysconfig/iptables file I have the following chain and definitions (using 
a group of IPs where noted such that the string reads 123.345.567.0/32 with the 
last part of the IP set to 0 to allow all within that domain).

*filter
:EDEX - [0:0]

-A INPUT -s (first IP address group)/32 -j EDEX
-A INPUT -s (second IP address group)/32 -j EDEX
-A INPUT -j EXTERNAL

-A EDEX -m state --state NEW -p tcp --dport 5672 -j ACCEPT
-A EDEX -m state --state NEW -p tcp --dport 5432 -j ACCEPT
-A EDEX -m state --state NEW -p tcp --dport 8080 -j ACCEPT
-A EDEX -m state --state NEW -p tcp --dport 9581 -j ACCEPT
-A EDEX -m state --state NEW -p tcp --dport 9582 -j ACCEPT
-A EDEX -j REJECT


What this does is allow connections from the stated IP address ranges for these 
ports only, which include the TCP connections that CAVE makes to EDEX.

I hope this helps you configure iptables, please let me know if you have more 
questions.
