NAME
NPF -- NetBSD packet filter
DESCRIPTION
NPF is a layer 3 packet filter, supporting IPv4 and IPv6 as well as layer 4 protocols such as TCP, UDP, and ICMP. It was designed with a focus on high performance, scalability, and modularity.

NPF offers the traditional set of features provided by packet filters. Some key features are: Stateful inspection (connection tracking). Network address translation (NAT). This includes static (stateless) and dynamic (stateful) translation, port transla- tion, bi-directional NAT, etc. IPv6-to-IPv6 network prefix translation (NPTv6). Tables for efficient IP sets. Application Level Gateways (e.g., to support traceroute). Use of BPF with just-in-time (JIT) compilation. Rule procedures and a framework for NPF extensions. Traffic normalisation (extension). Packet logging (extension). For a full set of features and their description, see the NPF documenta- tion website and other manual pages.
