According to ESRI documentation: http://server.arcgis.com/en/portal/latest/install/linux/about-the-arcgis-web-adaptor.htm
The webadapter for portal is hard coded to use 80 or 443. Is this true? If so, why? many webservers use other ports - like 8443 for example, Some organizations many not allow 80/443 - but will allow 8080/8443. Am I misunderstanding the documentation, and I can configure webadapter to use other ports, or is using 80/443 really a hard requirement?
