WireGuard is designed to be extended by third-party programs and scripts. This has been used to augment WireGuard with various features including more user-friendly management interfaces (including easier setting up of keys), logging, dynamic firewall updates, dynamic IP assignment, [15] and LDAP integration.

These uses do not result in IPv4 packets containing 0.0.0.0 and so are not governed by RFC 1122. [2] These meanings may not be consistent between operating systems. In both Windows and Linux, when selecting which of a host's IP address to use as a source IP, a program may specify INADDR_ANY ( 0.0.0.0 ).
UDP hole punching is a technology that leverages this trait to allow for dynamically setting up data tunnels over the internet. [6] ICMP messages are distinct from TCP and UDP and communicate control information of the network itself. A well-known example of this is the ping utility. [7] ICMP responses will be allowed back through the firewall.
ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems – including most embedded network administration software.
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.
Pi-hole functions similarly to a network firewall [dubious – [[Talk:Pi-hole#network firewall|discuss]]], meaning that advertisements and tracking domains are blocked for all devices behind it, whereas traditional advertisement blockers only run in a user's browser, and remove advertisements only on the same machine.
OPNsense has a web-based interface and can be used on the x86-64 platform. [5] Along with acting as a firewall, it has traffic shaping, load balancing, captive portal and virtual private network capabilities, and others can be added via plugins.
Split tunneling is a computer networking concept which allows a user to access dissimilar security domains like a public network (e.g., the Internet) and a local area network or wide area network at the same time, using the same or different network connections.
