Sonic Firewall

Sonic firewalling features provide various levels of protection for connected computers. By using one of the three levels of filtering, you can protect your systems from many common Internet threats. We suggest that you to select a level of protection which is appropriate for your type of Internet usage and your understanding of system security.

This document is intended to provide you with a brief overview of the firewalling options for your DSL service. These firewalling rule sets are not intended to be used as a replacement for full-featured hardware or software firewall solutions, but are designed to provide basic protection for specific ports and services.

Customers are encouraged to turn on automatic system updates (Windows users, see Windows Update, Mac users, see Apple Service & Support), and to enable any system level firewalls available. We also recommend the use an anti-virus package which is automaticly updated. While most viruses and system exploits which arrive via email are blocked by Sonic's email server anti-virus solutions, they may not be blocked by firewalling, and up to date anti-virus software is an important last line of defense.
