Drawing the line that separates internal and external networks, Firewall filters traffic based on IP address, protocol and port, which enables administrators to designate which systems and services (HTTP, FTP, etc.) are publicly available.
Firewall can be run as a transparent bridge to complement a pre-existing firewall and allows you to control inbound and/or outbound access to specific IPs and ports.
Open source and free under the GNU General Public License (GPL).
Easily blocks sessions based on simple rules.
Rules can be based on a variety of attributes.
This app is offered free of charge for unlimited use. Enjoy!
The status of the Firewall application provides you with basic information, including sessions passed, flagged, blocked, etc.
You can easily add rules to the Firewall app under the “Rules” tab. You can set up any type of custom rule, for example block and flag all traffic to or from a specific port.
With Reports, you can create any type of Firewall report. This report shows the “Top Scanned Hostnames” and allows you to drill-down to show more details.
