Question.
How do set up that internet user can access PCs local
webserver?
http://64.123.128.11:8080  does not work
http://64.123.128.11  will ask admin name and password of
zoom modem and lead to admin page of the modem

How do  i get it connect to webserver from the intermet
user?
Your help is greatly appreciate.
