Hello Marc,
I have my ISP ADSL modem ; PC router ; home network ( 192.168.0.0/24 )
and 44net. I have DYNDNS set. I use a default setting at my PC Router
to drop everything and have found if I do not have port forwarding set,
along with prerouting, connections are not possible.
If I remove the [ # ] a connection is possible but the connection to my
neighbour drops, this is the point I do not understand.
Removing the prerouting for the other ports stops connections on these
ports
Regards,
Ian..

Please explain to us why you think that you need port forwarding in

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..
