I just got WebAccess working, but there is an obvious problem in the information presented by the tool. Basically, when you go through the process as described in the documentation, using the 'advanced' option, the example url uses the INTERNAL port, not the external port.
I can't seem to attach a screen shot, so all I can say is, I left the default internal port at 9000, set the external port to 8082, and the 'WebAccess URL' was shown as https://(my home address).com:9000, when it should have shown: https://(my home address).com:8082.
