For quite some times my back-up way to access a Fritz!Box when the VPN itself failed was to SSH into a system behind it and use SSH port forwarding to access the Fritz!Box.
Seems that only works for older models with older firmware versions, but newer models with newer firmware now give a rebinding protection error.
I am not sure why it does this as technically there is no [Wayback/Archive] DNS rebinding – Wikipedia.
Regrettably, I could not find a way around this from the links below.

A few years ago I asked for some help figuring out what to whitelist so that winget can update its sources and install packages.
This is how I found out.

Most Fritz!Box VoIP configurations have a phone number configured to only work on telephony devices (i.e. handsets) on the same Fritz!Box.
But it is possible to define a telephony device that itself is another VoIP end-point.
This way you can hook a second (or more) Fritz!Box up to the phone number(s) of the first Fritz!Box.
I am using this for two reasons:
Below is how to get this going, assuming the first Fritz!Box is a 7490 running firmware 7.29 and the second is a a 7360 with firmware 6.33 (other versions and firmware versions vary slightly).
But first the related post: Many links about free modem/router choice and their configurations for the Dutch KPN internet/VoIP provider where I figured out that just using a 7360 won’t cut it any more.

My ISP did auto-update the Fritz!Box, but did not send release-notes, so I was not aware this feature had been added eons ago:
[Wayback/Archive] thuddevort on Twitter: “@jpluimers @wijnands @b0rk @xs4all You can disable the extra confirmation under System > FRITZ!Box Users > Additional Confirmation”.
I know a second factor is better for security, but doing that on both sites at the same time when setting up LAN2LAN VPN is tough (Fritz!Box names this either “LAN-LAN coupling” or “VPN Connections between the FRITZ!Box and Other Networks”.
A better feature at the same configuration page is instead of disabling, enabling to confirm using apps like Google Authenticator and Authy:

A while ago, I had to redo all of the existing Fritz!Box LAN2LAN VPN connections.
It was a pain for many reasons, reminding me of the pain
This is why it was so painful:

Deze moet je in een Fritz!Box zetten om TV-West op een PC te kunnen:
cloudfront.net omroepwest.bbvms.com i.regiogroei.cloud static.regiogroei.cloud cdn.primed.io omroepwest.nl

Translation of solving a broken xs4all connection:
Solved. Summary:
- Liander and UPS functiond, so both Fritz!Box and NTU had power
- NTU LEDs show Power and Glass, but no Ethernet
- Fritz!Box has green Power and WLAN LEDs and a red Info LED
Solution was cold reboot of NTU.
I also neatly tucked away the NTU power cord for an additional 8 minutes extra down time: [Wayback/Archive] mwgp ping – wiert.me

Early spring 2023 I posted Reminder to self: check if FritzOS 7.50 has become available for Fritz!Box 7490 because it would (likely partially) introduce WireGuard support as I knew it had been available for other Fritz!Box devices since december 2022: [Wayback/Archive] Fritzbox: AVM startet die Verteilung von FritzOS 7.50 | heise online
Das Betriebssystem FritzOS 7.50 für Fritzbox-Router ist fertig. Mit dabei sind das Wireguard-VPN und Verbesserungen im Smart-Home-Funktionsumfang.
Finally, early september 2023 my Fritz!Box 7490 devices updated from firmware version 7.29 to 7.57 so apparently it took AVM quite a while to test and stabilise the new features on Fritz!Box 7490.
The final push for 7.57 might actually be a security issue in prior versions that already looks like being exploited according to [Wayback/Archive] AVM: Fritzbox-Firmware 7.57 und 7.31 stopfen Sicherheitsleck | heise online
Fritzbox-Update: Bereits angegriffene Sicherheitslücke wahrscheinlich
In Internetforen finden sich Hinweise darauf, dass die mit dem Update geschlossene Sicherheitslücke bereits angegriffen wird. Den Gerüchten zufolge können Angreifer Zugriff durch den HTTPS-Port 443 erlangen und hätten dann Zugangsdaten zur Fritzbox sowie PPP-Zugangsdaten verändert. Dadurch sei kein Internetzugang mehr möglich, und auch der Zugriff auf die Fritzbox werde verhindert. Einzig ein Werksreset helfe dann, um wieder Zugriff zu erlangen.
The odd thing of the upgrade logs is that the fiber connected 7490 mentioning a DSL settings reset, but the DSL connected 7490 didn’t:

I had to add the below to the firewall permission list of a Fritz!Box to allow watching NPO Start, the free Video on Demand service of the Dutch public broadcasting system:

Given my health uncertainty, I am looking for maintainers for the fritzcap project (it captures calls from a Fritz!Box modem/router and is written in Python).
The fritzcap project was originally started in2007 by [Wayback/Archive] spongebob | IP Phone Forum, first as a binary fritzcap.exe Windows executable (see his first post at [Wayback/Archive] FritzBox: Tool für Etherreal Trace und Audiodaten-Extraktion | IP Phone Forum). In 2010 it became an open source Python project at [Wayback/Archive] Google Code Archive – Long-term storage for Google Code Project Hosting.
