Netfilter is a framework that provides a set of hooks within the Linux kernel for intercepting and manipulating network packets. The best-known component on top of Netfilter is the firewall which filters packets, but the hooks are also used by other components which perform network address translation, stateful tracking and packet enqueueing to user space. The name Netfilter also refers to the name of the project that provides a set of firewalling tools for Linux. These components are usually loadable kernel modules, although the project also offers a set of userspace tools and libraries. Backward compatibility support for ipchains has been recently removed.
iptables is the name of the user space tool by which administrators create rules for the packet filtering (both inbound and outbound) and NAT modules. While technically iptables is merely the tool which controls the packet filtering and NAT rules within the kernel, the name iptables is often used to refer to the entire firewalling infrastructure, including the kernel-level Xtables (sub)framework that provides the API for match and target modules and the actual firewall table traversal for IPv4, IPv6 and ARP. iptables is a standard component of all modern Linux distributions.
conntrack is the name for the tool that allows manual manipulation of connection tracking and NAT entries.
