Servidor local não é roteado através de ethernet

Question

Não consigo acessar um servidor local do Raspberry Pi ( 192.168.0.155 ) em minha rede doméstica pela Ethernet, embora eu possa fazer o ssh perfeitamente compatível com o Wi-Fi.

Eu tenho a conectividade com a Internet muito bem por meio de ambas as interfaces, e o mesmo comportamento ocorre em outro Macbook (pode chegar ao servidor via wifi, mas não através de ethernet).

Todos os cabos ethernet simplesmente funcionam no meu roteador doméstico (executando o DD-WRT), que também serve como ponto de acesso sem fio.

Aqui está minha saída netstat -rn ao usar ethernet (através de uma estação Thunderbolt) do meu Macbook Pro ( 192.168.0.176 ):

Redefini as rotas várias vezes, reiniciei os laptops e o roteador e alterei o IP no servidor Pi, mas o problema persistiu.
