ALGUÉM já fez o planeamento da eletricidade de uma CASA de origem ou com obras qual são as dicas que fizeram para o Prewire de uma casa com CAT6 (alarme com cabos network, tablets na parede, HDMI over Ethernet, cat6 no tecto para app, bastidor na garagem, homeassistant, shelly). Eu tenho alguns requisitos mas gostava de saber a vossa opinião especialmente na parte de HDMI over ehternet.

Eu vou tentar centralizar tudo num documento, mas a ideia era seria se ganhares o "euromilhões"

1. Configurar IPv4 estático e IPv6 estático no pihole (YMMV)
    192.168.1.2 e 2001:818:xxxx::192:168:1:2 no meu caso
    
2. Configurar DNS uplink do pihole igual ao IP do Router (192.168.1.1)
    
3. Configurar Router

Huawei HS8247W (Smart Router 2)
  1. Configurações Avançadas -> LAN -> Configuração de DHCP
      Servidor DNS Primário: 192.168.1.2

Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)
