Estou tentando por alguns dias para conseguir isso, mas até agora não consegui. Minha situação é bem parecida com a VPN no SSID # 2 (OpenWRT) , mas um pouco diferente .
Na minha situação, estou usando o OpenVPN; Eu tenho um SSID separado para meus 2,4ghz e 5ghz e uma instância separada em 5ghz que deve passar pelo OpenVPN.
O que entendo é que preciso examinar o roteamento IP, mas meu conhecimento de rede é limitado demais para isso.
Eu corro minhas instâncias "regulares" no intervalo de IP 192.168.1.x A instância que deve passar pela VPN está em 192.168.55.x
Na resposta da pergunta comparada, tentei "ip route add 192.168.55.0/24 dev tun0", mas isso me dá um erro.
Não é possível encontrar o dispositivo "tun0"
Obviamente tun0 é o openvpn.
Eu, literalmente, não tenho idéia de como resolver isso ou em que direção preciso ir. Talvez alguém possa me ajudar a fazer isso.
Muito obrigado antecipadamente:)
edite: Eu tentei as etapas de Como rotear uma sub-rede específica para uma Túnel VPN isso pode ser visto na configuração openvpn também. sem sucesso embora.
