[arm-allstar] Port number issue

[Simon Keys]

So here is my scenario:
1xRpi2 with v1 build, node 42098
1xRpi3 with v1.5 build, node 29023
1x wireless router, port 4569 opened.

Rpi2 has ip of 192.168.1.145 and IAX port 4569.  This successfully
registers and allows incoming connections.
Rpi3 has ip of 192.168.1.142 and IAX port 4571.  This is set in iax.conf
and on allistarlink.org.  This node also registers successfully.

I have also set the [nodes] section in rpt.conf on both servers correctly
(although I will copy/paste here when I get home).

On Rpi3 iax2 show registry gives 4569.  lsnodes gives 4569 also.  Strange
and I think this is where the problem is.

I can connect from 29023 to 42098 successfully.  However when I try to
connect from 42098 to 29023
 it times out with network congestion message.

Do I need to open port 4571 to allow local inter-node connections?
