Firewall

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.
