[arm-allstar] Connect OUT but not IN

[David]

I have an RPi3 server running V1.5 with two nodes.  The main node is 
connected to a repeater and is private.  The second node is registered 
and is configured as pseudo.
Using Supermon I can connect the private node to the registered node but 
not the other way.
This is also true connecting to other private nodes outside of my LAN, 
that is, this one private node only connects going OUT to other nodes.  
I believe I understand how private nodes are configured since I have 
others connecting just fine going IN or OUT.

How is it that connection between two nodes on the same server can only 
be initiated from one of them?

I don't see any errors on the Asterisk or Linux logs after the connect 
attempt fails.
