Does not ping VPN server tunnel

madrada

Buenas tardes,

Llevo un par de días configurando el OpenVPN, lo he hecho muchas veces pero ahora mismo, me está dando un error que no llego a el.

Tengo el OpenVPN server instalado en un Win server 2016. Desde el cliente se conecta bien, pero no puedo entrar a las carpetas de red, y tampoco hacer ping a los equipos de red. Tampoco al servidor.

Lo que he ido quitando cortafuegos, desabilitando los de winfdows también y aun así no hace nada. He realizado un tracert desde el cliente y desde el server. En el cliente no me reconoce el tunel, es decir me da una ip 10.10.8.6, hace ping a esa IP pero a la 10.10.8.1 que es la del servidor no.

Desde el servidor tampoco me hace ping a su tunel IP 10.10.8.1, se que el problema está en el servidor, tengo todo cortafuegos y demás quitado.

Alguna idea?

gracias,
.

Good afternoon,

I've been configuring OpenVPN for a couple of days, I've done it many times but right now, it's giving me an error that I can't get to it.

I have the OpenVPN server installed on a Win server 2016. From the client it connects well, but I cannot enter the network folders, and neither can I ping the network computers. Nor to the server.

What I have been removing firewalls, disabling those of winfdows as well and still does nothing. I have made a tracert from the client and from the server. The tunnel does not recognize me in the client, that is, it gives me an IP 10.10.8.6, it pings that IP but the 10.10.8.1 that is the server's one.

From the server it does not ping me its IP 10.10.8.1 tunnel either, I know the problem is with the server, I have all firewalls and other removed.

Any ideas?

thanks,

Pippin

English please,

Thanks.

You must enable the "Windows DHCP Client Service"

madrada

OK, now I can ping the tunnel ip server from the client, but now I cant ping to server ip address 192.168.1.33, so I cant access to shared folders etc...

madrada

sorry, from the server I cant ping to client ip tunnel.

madrada

Check your firewalls,

madrada

Firewalls are disabled.

you are not setting NAT and ip forward so you can ping real server ip . only virtual ip you can so from route 10.10.8.0 it need to NAT to real ip just come here the instruction to help you.
