Adding OnlineFamily.Norton servers to proxy server

Forgive me if my post seems sharp - but I have been trying to get this system to work for 3 days, spending 4 - 6 hours a day.

 

I finally think I found the problem - but tech issue section did not state "HOW" to do this - there seems to be an assumption that an end user knows how to do the explanations give in the tech support section.

 

How do you add onlineFamily.Norton to the exception list?

 

Need help very, very soon.  Grandson coming home in 4 hours and I need this running!!

 

thanks, Granny 7
