There are some hacking tools for Fritzboxes out there but Avm themselves are pretty good at supporting their hardware for a long time. The 7490 was released in April 2013 and just received another security update (January 2025). Quite a long support time. To me they seem to be the best standard solution that can also be setup by a "beginner" user.
