Hello Doug,

I have solved my problem !!!  Here's what I had and what I did..

In my iptables for Allstar I had

$IPTABLES -A FORWARD -d 44.131.8.30 -j ACCEPT -p udp --dport 4567
$IPTABLES -A FORWARD -d 44.131.8.29 -j ACCEPT -p udp --dport 4568
$IPTABLES -A FORWARD -d 44.131.8.0/27 -j ACCEPT -p tcp -m tcp --dport 
5035:5038

I then added the line

$IPTABLES -t nat -A PREROUTING -p  udp --dport   4567 -j DNAT 
--to-destination  44.131.8.30

which allowed me to connect from the WebTransceiver to my BBB. Success 
!!!!

My ISP also provides my TV etc and the subnets are restricted to either 
192.x.x.x or 172.x.x.x hence my " own " router to allow use of a 
different subnet.

As I previously said I am learning about IPtables and the next hurdle I 
need to get over is why I have a connection on another port that fails 
when I have a [ PREROUTING ] line in the table and connects when there 
is no [ PREROUTING ] line against it.

Regards,

Ian..
