Want to configure UPnP on EdgeRouter-4?

Don't do it!

Introduction

As a former sysadmin that once helped ride herd over around 1,000 servers, of which around 10% were Internet-facing, I've never been a fan of autoconfiguation when it comes to punching holes through the firewall. I've seen the tripwire logs, and it's sobering.

The Problem

So enabling UPnP on my EdgeRouter-4 wasn't something I had on the roadmap, but when I ran into difficulty getting DLNA to work on the default VLAN, I thought it was worth looking into (never mind that, as I later learned, having UPnP turned on wasn't going make a bit of difference on my local network: another reason that mastering theory should always come before practice).

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export to tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

	#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
	; #Warn ; Enable warnings to assist with detecting common errors.
	SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
	SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.

	# A co-worker of mine stumbled upon this nifty blog article on how to make a text-to-speech call using PowerShell.
	# The article gives two examples:
	# - Call the SAPI.SPVoice COM object
	# - Load the reference to System.Speech
	# Where can this come in fun? Well, if you throw PSRemoting in, of course! In my testing, if you use the second method (or the pared down script below) you can make your victim's computer start talking to him or her. Here's how you do it:
	# 1. Provide a distraction so that your victim leaves their computer unlocked, and make yourself administrator on their workstation (only needed if you aren't already an admin!)
	# 2. Enable PSRemoting on their workstation. A method for doing this would be using PSExec:
