WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]

A true DMZ is a network that contains hosts accessible from the internet with only the exterior, or border, router between them. These hosts are not protected by a screening router." "A screened subnet may also be a collection of hosts on a subnet, but these are located behind a screening router.
It is included in Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 10. [1] It is also implemented by systemd-resolved on Linux. [2] LLMNR is defined in RFC 4795 but was not adopted as an IETF standard. [3] As of April 2022, Microsoft has begun the process of phasing out both LLMNR and NetBIOS name resolution in favour of mDNS. [4]
pfSense is a firewall/router computer software distribution based on FreeBSD. The open source pfSense Community Edition (CE) and pfSense Plus is installed on a physical computer or a virtual machine to make a dedicated firewall/router for a network. [ 3 ]
The router's firewall exposes all ports on the DMZ host to the external network and hinders no inbound traffic from the outside going to the DMZ host. [8] [9] This is a less secure alternative to port forwarding, which only exposes a handful of ports. This feature must be avoided, except when: [9]
There are two common network configurations that include bastion hosts and their placement. The first requires two firewalls, with bastion hosts sitting between the first "outside world" firewall, and an inside firewall, [3]: 33 in a DMZ. Often, smaller networks do not have multiple firewalls, so if only one firewall exists in a network ...
