Olá, comunidade!
Estou usando o Linux Mint como desktop principal. Pensei em melhorar a privacidade da minha conexão configurando o sistema para usar DNS‑over‑TLS (DoT)… por exemplo, os servidores DNS seguros da AdGuard, Mullvad (Ad‑block/Extended) ou Cloudflare.
Já li alguns tutoriais, mas ainda estou receoso de aplicar mudanças que possam “quebrar” o sistema ou deixar a rede inutilizável.
Dito isso, Qual a forma mais segura de habilitar DoT no Mint? Devo usar systemd-resolved, dnscrypt‑proxy, stubby ou outra ferramenta?
Existe alguma aplicação “tudo‑em‑um” que gerencie DNS, firewall, proxy sendo algo similar ao ReThink DNS que encontrei nos smartphones?
Agradeço muito qualquer ajuda, tutoriais detalhados, scripts prontos ou recomendações de aplicativos que facilitem esse processo.
