OpenVPN Support Forum

I have a small network setup on rental equipment. This includes a camera/NAS and other services.

This network uses a 4G modem for internet acces when near shore and client internet when out of 4G service. Public IP adresses and firewalls therefore are not fixed and not always in our control to change.

I want to reach the network services from home/office without the use of TeamViewer or other tools that run on a pc.

I was hoping to setup a cloud OpenVPN where a Draytek 2729 router could log in to and provide the services to the cloud OpenVPN.
By connecting to the same VPN from my home/office pc, I hope to contact the remote services.

I tried setting up Networks, Hosts, etc, but I cannot seem to get something up and running. Could someone point me towards the right direction?

For a test setup I try to ping my CCTV from a notebook connected to a phone hotspot. A local pc uses OpenVPN connect to setup a network or host. The notebook can connect via OpenVPN connect as well but I cannot ping the camera. I know that there is a large knwoledge base here, but for the network-noob that I am, most is not readable/clear to me.

I have 'solved' the issue by setting up a host. A notebook in the remote network can use the host connector to connect to the VPN cloud as a host.

I can now connect to the VPN cloud as a user to approach the host on the VPN ip to use RDP.

I am now depending on a remote pc/notebook so that's not super, but for now it's acceptable + 'easy' to setup

Hello Valk,

Sorry, I know the Draytek routers, and they're extremely limited in their capabilities. I don't think it's possible to connect that directly.

However, when OpenVPN3 Linux client v14 beta is out, it will become available for Ubuntu 20 on ARM64. That means a Raspberry Pi could do the job. We'll obviously prepare the necessary documentation for this, although I cannot give you an exact ETA.

You could also now use Raspberry Pi with the normal OpenVPN2 Linux client - that also works just fine with both Access Server and Cloud, and you can set that up even now.

Kind regards,
Johan

Do you have full subnet access like this?

Hello deanfourie,

That depends on whether you set up this VPN client as just a normal user, or as a connector. A connector is used to connect a whole subnet through one VPN tunnel to OpenVPN Cloud. You can use NAT or routing. With routing it requires your network to cooperate in terms of some static routes set up on your end.

Kind regards,
Johan
