Eep, losing the manual's never a good idea!
I would contact your ISP, seemingly BellSouth, for further help with that service. I can't help you there myself with confidence, let the professionals play around with your Internet port settings. You might find
this page useful. They may also be able to help you with WinProxy, however, you might try getting technical help with WinProxy using the contact details on
this page.
Hope I've been of use
Regards,
