The FiOS Router features three pre-defined firewall security levels: Maximum,
Typical, and Minimum. The table below summarizes the behavior of the FiOS
Router for each of the three security levels.

These services include Telnet, FTP, HTTP, HTTPS, DNS, IMAP, POP3 and SMTP.
Note: Some applications (such as some Internet messengers and peer-to-peer
client applications) tend to use these ports if they cannot connect with their
own default ports. When applying this behavior, these applications will not be
blocked outbound, even at the Maximum Security level.
