Firewalls draw the line which separates internal and external networks.  Untangle’s Firewall filters traffic based on IP address, protocol and ports that allow administrators to:  

• Designate which systems and services (http, ftp, etc.) are publicly available
• Create a DMZ and perform NAT (with Router)
• Run as a transparent bridge to complement existing hardware

Firewall can both monitor and block traffic sessions based on simple, yet flexible rules. The Firewall enables you to control traffic by:

• Protocol
• Source address or port
• Destination address or port

You can build your own list of rules, and dictate how the Firewall must respond.

The Firewall is the most basic security element to hide your network from the outside and control all external access points (also known as ports). It lets you block unwanted activity and protect your network.

You can build a list of rules that meets your unique needs—control traffic by protocol, source address or port, destination address or port, and set default actions.

Firewall evaluates traffic traveling across your network by applying your rules until a block/pass verdict is reached or a default action is taken.

Key Features:
