Openvpn network

gcp900

Hi guys!

I am new in the world of VPN but I am learning fast. Anyway, I have got some questions about the VPN I am creating right now.

I want to create a VPN because I have got a house with some devices to control remotely. That house has a 3g internet conection and in Spain it is almost impossible to get a public ip through a 3g conection, so that the ip that my remote house has is a private ip which doesn't allow me to get into the devices.

What I want to do is to use a router as a client of an Openvpn network and as a gateway to access the devices behind it (the router that is creating the network the devices are conect to right now). But the fact is the router must to be a client of the network not a server, because a server needs a public ip which is not the case. On the other side, I would have another computer being a client of the same Openvpn network which would be allowed to communicate with the other part of the network. That would be the main structure. And where would the server be? ok so, the idea is to use a free openvpn server like vpnbook.com, but I am not sure if it would be possible the comunication between clients through one of this servers. If it wouldn't I would have to setup my own server, but I would like to avoid this option if it is possible.

Finally, what do you think? I am on the correct way? Sorry if there is something so much simply but I am starting.

Thanks a lot for your opinions!!

First off - this is not related to OpenVPN Access Server Product.

Hi gcp900,

with regard to your problems:

I don't really understand what you mean by this .. if your house in Spain is connected to the internet the it must have an IP address ..
although you may only receive an IPv6 address in some cases.

gcp900 wroteWhat I want to do is to use a router as a client of an Openvpn network and as a gateway to access the devices behind it

This is normal and can be done.

gcp900 wrotethe idea is to use a free openvpn server like vpnbook.com

I do not believe vpnbook operates such a service.

You need your own private VPN server with a public IP address possibly at your real home or work.
Or even a rented server: put "rent a server" into google and take your pick.

Once you have your personal VPN server up and running you can create your VPN and access the devices behind your client in Spain fairly easily. This presumes you are using another computer which is a client of your VPN.

Hope that helps..

Thanks for your answer and sorry for posting in the wrong forum. I was not sure which forum was more appropriate.

I don't really understand what you mean by this .. if your house in Spain is connected to the internet the it must have an IP address ..

In Spain 3g connections are behind a NAT as it were a private network, so if you use services on the internet as a client there's no problem but if you try to use that connection to access a server it is impossible because there's a NAT you can not configure with port forwarding. Do you know what I mean? It is like if your were in a LAN with a router you can not forward, you can go out but not making a request from outside.

Your answer has clarified many things to me. Regarding to the server probably I would set up a raspberry pi for keeping it working in my house. I think it's the best option.

Lastly, I realized there were some grammatical english mistakes in the text but I couldn't change them 🙁

Thanks!

One question again. To access the devices behind a OpenVPN client do I have to configure a VPN in bridge mode? This is a point I misunderstand. Once I have configured the VPN would it be as simple as write the address of the other client on the browser??

Thanks!!

No problem ..

Now I see what you mean ..

Sounds like a suitable approach.

Read the HOWTO particularly this section for your needs:

I have set up the server and the network and everything works fine. The problem right now is how to reach other clients inside the network (I can ping between servers and clients, but not between clients). I suppose I have to configure the server in bridge mode...

You do not require a bridge .. unless you need Broadcast packets or another protocol other than TCP/IP (such as IPX).
