A firewall is a system designed to prevent unauthorized access to or from a network.
If any security software such as anti-spyware software is running on your computer, it blocks communication between your computer and printer via EpsonNet Setup and prevents the printer from being searched and configured.
Be sure to disable any security software, or register EpsonNet Setup as an exception in the security software to continue installation using EpsonNet Setup.
Refer to the FAQ page on the Epson Web site on how to disable security software installed on your computer. You can jump to the Epson Web site using the link in the wizard.
