All Apache Tomcat web applications may be referenced via port 80, so external URL's will not need any port declaration.
Sophisticated and buggy installation

Apache Tomcat Connector Installation
If you use IIS (Internet Information Services 7.5, 8.0, 8.5 or 10) as web server and Apache Tomcat as servlet engine then you may want to install the Apache Tomcat Connector.
This requires the installation of specific components of IIS (Internet Information Services). Open the Control Panel -> Programs and Features -> Turn Windows features on or off and expand the Internet Information Services feature. Verify that the IIS components listed below are turned on.
Note: The IIS components are only minimum requirements. If other IIS components are installed, they do not need to be removed.
