Acessa os clientes do roteador pela rede VPN

Question

Eu tenho a seguinte rede VPN, e o problema é, como acessar o raspberry pi ou qualquer OpenWRT Router VPN CLIENT com o endereço IP 192.168.8.X.

Eu posso acessar o OpenWRT VPN CLIENT com 10.8.0.6 do meu laptop, mas nenhuma resposta para o ping 192.168.8.1.

Além disso, posso acessar o IP 192.168.1.1 do meu laptop.

E para o arquivo de configuração do servidor VPN, eu tenho:

config openvpn 'myvpn'
        option enabled '1'
        option verb '3'
        option proto 'udp'

        option dev 'tun'
        option dev 'tun0'
        option topology subnet
        option pull

        option dh '/etc/openvpn/dh2048.pem'
        option port 'XXXX'
        option client_to_client '1'
        option down '/usr/bin/ovpn-down'

        list push 'route 192.168.1.0 255.255.255.0'
        list push 'route 192.168.10.0 255.255.255.0'
        list push 'route 192.168.8.0 255.255.255.0'

        list push 'dhcp-option DNS 192.168.10.1'
        list push 'dhcp-option DNS 192.168.8.1'

        list push 'route 10.8.0.1 255.255.255.255'
        list push 'route 10.8.0.0 255.255.255.0'

        list push 'redirect-gateway def1'

Adicionando novas informações:

Além disso, eu tentei sem a opção list push 'route 192.168.8.0 255.255.255.0' e ainda não consigo acessar o ip da rede 192.168.8.1.

Alguma idéia?
