Sorry to hear about your injuries.
The Tripp-Lite UPS actually is a device called an Uninterruptible Power
Supply that protects your computer and related electronic equipment in
the event of a power fail. Usually, these are somewhat configurable, and
yours may be configurable using the UPnP capability of Windows.
Without the model number, I can't tell if your Bell South modem does or
does not incorporate a router.
If I were you, I'd leave UPnP UNchecked in the Windows Firewall
exception list. This will prevent you from using UPnP to configure any
UPnP-compatible networked devices, but because you weren't aware of how
to do this anyway, it's no big loss. Almost any device that *could* have
been configured using UPnP can *also* be configured by directly
accessing a web page through a browser (e.g., Internet Explorer,
Firefox, etc.). And if you ever really need to use UPnP, you can just
allow it by checking the box in the firewall exception list.
