'''Shorewall''' is an [[open-source software|open source]] [[firewall (networking)|firewall]] tool for [[Linux]] that builds upon the [[Netfilter]] ([[iptables]]/[[ipchains]]) system built into the [[Linux kernel]], making it easier to manage more complex configuration schemes by providing a higher level of abstraction for describing rules using text files. Its documentation is hosted on shorewall.org, while the latest code is hosted at https://gitlab.com/shorewall/code.
