Netfilter,在Linux內核中的一個軟體框架,用於管理網路封包。不僅具有網路位址轉換(NAT)的功能,也具備封包內容修改、以及封包過濾等防火牆功能。利用運作於使用者空間的應用軟體,如iptables、、和arptables等,來控制Netfilter,系統管理者可以管理通過Linux作業系統的各種網路封包。1990年代,Netfilter在Linux 2.3.15版時進入Linux內核,正式應用於Linux 2.4版。 現今許多市面上許多的IP分享器或無線網路路由器(Wireless router),多是嵌入式Linux平台,並利用Netfilter的封包處理能力,提供NAT以及防火牆的功能。此外,Netfilter平台的模組化設計使得功能具可擴充性,以及Linux核心本身屬於開放的原始碼,能夠免費取得原始碼進行修改與擴充。Netfilter平台中制定了五個封包的掛載點(Hook),分別是PRE_ROUTING、INPUT、OUTPUT、FORWARD與POST_ROUTING。
