Can't access tomcat externally

[Nathan Fuchs]

I just installed Tomcat with the default settings (port 8080), version 7.0 using JRE 1.7.0 on windows 7 professional.
Everything works fine if I keep it as port 8080, but I want it to use port 80, so I can use it as a regular http server. If I install it using port 80, only locahost can access it.

If I type "localhost/" in my browser, I can access tomcat just fine, but if I use "127.0.0.1/" or "192.168.1.102/" I get the error "Oops! This link appears to be broken."
This is using the default server.xml file.

Any help is greatly appreciated.
