My network is not particularly complicated. It is the ISP router that manages the biber connection (FTTH). So I have to have that specific ISP provided box, which offers me some more or less crappy features (DNS, DHCP, ...).

If I want to use Pihole for DHCP (because it handles internal registration well) and DNS (because if offers filtering) I need to disable DHCP on the ISP router. But since the TV is handled through IPv6 I need to understand it to make sure that that stack is correctly implemented.

Then I have two mesh networks (tailscale and Wireguard as a backup because I manage family networks that are not available from internet) and a docker stack which has its own surprises.

I would love to put a linux box as the egress router and handle everything there (the fiber, DNS, DHCP, etc.) but it is not possible with the provider because the SFP is proprietary (sort of)).

I am really happy to have a relatively stable 1 Gbps fiber connection so I am not complaining - but doing things exactly as I would wish is not always possible.
