Configuring CC

I have calibre already configured to go to a URL HTTP://someURL.com:8080

If I launch this in a browser I am then prompted for user ID / pw and can then access my libraries on my Iphone from anywhere that I have internet access.

What is the proper setup for this inside CC?

Should the URL be manually configured and the port listed on the next line?

If I attempt to manually configure it I receive the ID/pw prompt but then it fails saying it cannot find the content server.

If I am home and on the same home network as my calibre content server it will connect assuming I've left the manual config blank.

Thanks!
