    IPTables won't forward TCP port 9453

    Hi Folks!

    I have been using a Slackware machine as internet gateway for some time. I also have been forwarding TCP ports succesfully (for example ports 2500, 2501, 55800).

    Now I have to redirect port 9453 and it won't work. When I run an online port scan, it gives "Stealth" which means that the Slackware machine is just dropping packets arriving at port 9453.

    I use the following commands to forward ports:

    iptables -A FORWARD -i eth0 -o eth1 -p tcp --dport 9453 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

    iptables -A PREROUTING -t nat -p tcp -d --dport 9453 -j DNAT --to



    Same goes for port 1043.

    Sorry folks,

    The problem is solved. Some n00b installed a firewall on the internal pc.
