Difficulty with remote AND local access

I found this thread:

It looks as though my problem may have been solved. I will be back to let you know if I am consistently able to access the server from my desktop pc. If the problem persists, I’ll also let you know. Disabling the Xfinity protection as mentioned in the above thread seems to have solved the problem, though.

If this is the solution I want to thank you for putting the time in to help me!!!
