The freely available Linux operating system includes a number of facilities for efficient kernel-level IP packet filtering and screening. The acceptance and forwarding of IP packets can be regulated by specifying filter rules, using packet and network device characteristics, such as IP addresses, port numbers, IP flags, and incoming or outgoing interfaces. Linux also provides a facility comparable (to some extend) with transparent proxies (not requiring any changes for users or application software), which is implemented as part of the IP firewall module and can be configured using a similar set of rules.
