Please explain to us why you think that you need port forwarding in the first place.

Hello,
As someone new to the intricacies of port forwarding I have been puzzled why I cannot
maintain a connection when I have the entry shown below for port 7300 active yet
connections via port 6300 and 8000 work as expected.
$IPTABLES -A FORWARD -d 44.131.8.0/27 -p tcp -m tcp --dport 6300:6310 -j ACCEPT
$IPTABLES -A FORWARD -d 44.131.8.0/27 -p tcp -m tcp --dport 7300:7310 -j ACCEPT
$IPTABLES -A FORWARD -d 44.131.8.0/27 -p tcp -m tcp --dport 8000:8011 -j ACCEPT
$IPTABLES -t nat -A PREROUTING -p tcp --dport 6300 -j DNAT --to-destination
44.131.8.16:6300
#$IPTABLES -t nat -A PREROUTING -p tcp --dport 7300 -j DNAT --to-destination
44.131.8.16:7300
$IPTABLES -t nat -A PREROUTING -p tcp --dport 8000 -j DNAT --to-destination
44.131.8.16:8000
Placing a [ # ] as shown allows the connections.
Regards,
Ian..
