Why does Tomcat work with port 8080 but not 80?

Question

I have started and tested Tomcat under Port 8080 (default). Now I altered the connector port to 80 and restarted Tomcat, nothing will show on my minimal Debian 6.0 installa

If nothing of the commented before works (like it happened to me), you can direct the traffic from the port 80 to the 8080.

To do it:

In a nutshell, type this three commands in a terminal:

$ sudo iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
$ sudo iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT
$ sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
