Why does Tomcat work with port 8080 but not 80?
go to /etc/default/tomcat6 and change #AUTHBIND=no to AUTHBIND=yes
# If you run Tomcat on port numbers that are all higher than 1023, then you # do not need authbind. It is used for binding Tomcat to lower port numbers. # NOTE: authbind works only with IPv4. Do not enable it when using IPv6. # (yes/no, default: no) #AUTHBIND=no
If nothing of the commented before works (like it happened to me), you can direct the traffic from the port 80 to the 8080.

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
