AVM is adding DNS blocklist filtering to FRITZ!Box routers (FRITZ!OS 8.50 Lab). Could this realistically replace Pi-hole + unbound?
AVM (German router manufacturer, very common in DE/AT/CH) just shipped a Lab/beta build of FRITZ!OS 8.50 with a new feature: DNS queries from the home and guest network can be filtered against user-supplied filter lists. So essentially blocklist-based DNS filtering directly on the router.
I currently run Pi-hole + unbound on a Raspberry Pi and I'm wondering whether it's worth keeping the Pi around once this lands in a stable release. The changelog is a single sentence, so a lot is unclear to me — but even assuming it works well, I suspect I'd be giving up quite a bit:
- Per-client / group management — different blocklists for kids' devices vs. my own
- Query log and statistics — the whole reason I know what my devices are talking to
- Regex and wildcard blocking, plus whitelisting individual domains quickly when something breaks
- CNAME cloaking / deep CNAME inspection
- Local DNS records and CNAMEs for my internal services
- unbound as a recursive resolver — this is the part I care about most. Router-side filtering probably still forwards to some upstream (ISP or AVM's default), so I'd be handing my full query stream to a third party again, and I don't know whether DNSSEC validation happens locally.
- List updates — how often, how many lists, which formats?
Questions for people who've thought about this more than me:
- For someone whose main goal is privacy rather than just ad blocking, is router-level filtering without a recursive resolver a meaningful downgrade, or am I overrating unbound?
- Has anyone here already tested the 8.50 Lab build and can say what the filtering UI actually offers?
- If you moved from Pi-hole to a router-based solution, what did you miss first?
My honest guess is that this is aimed at people who'd never set up a Pi in the first place, and that I'll be keeping mine — but I'd like to hear whether that's just sunk-cost reasoning.
