Desktop and Mobile Clients
The OpenVPN app has been tested with the following clients:
How to connect on Ubuntu 16.04
- Install the Network Manager OpenVPN plugin
sudo apt-get install network-manager-openvpn-gnome
- Download the .ovpn embedded certs config file from the OpenVPN app
- Open Network Manager,
Import from file...
This app has a built-in DNS server (which is pushed to clients). This DNS server
allows resolution of connected clients using
If you have an internal DNS server, you can configure Cloudron to forward all DNS queries to the internal DNS server. This way clients can resolve internal addresses as well.
You can customize various settings by editing
the Web terminal. Some popular options are
By default, the VPN uses the 10.8.0.0/24 network. If you happen to connect to multiple VPN networks at the same time, this can cause an address conflict. To change the network to say 10.12.0.0, edit the file as below and restart the app.
server 10.12.0.0 255.255.255.0 push "dhcp-option DNS 10.12.0.1"
Inter client connectivity
By default, the app allows clients to talk to each other. To disable this, edit the file as below and restart the app.
By default, clients are configured to route all traffic via the VPN. If you disable this, you would want to push custom routes for the network and hosts behind the VPN. For example, edit the file as below and restart the app.
# push "redirect-gateway def1 bypass-dhcp" push "route 126.96.36.199 255.255.255.255" push "route 188.8.131.52 255.255.255.0"
The OpenVPN app provides a tunnel to channel all the traffic from your devices via the Cloudron. Websites and services that you visit will not see the IP address of your devices but they will see the IP address and possibly the RDNS hostname of your Cloudron.
You can check what sort of information can be gathered from your Cloudron's IP address using ipleak.net.
Custom Client Configuration
Custom Client Configuration allows the OpenVPN admin to assign a specific IP address to a client or push specific options such as compression and DNS server to a client.
To add custom settings:
/app/data/openvpn.confand add the following line:
Create the directory
You can create custom client configs in this directory by creating files with the name
[username]_[devicename]. You can also create a file named
DEFAULTwhich will be used if no device specific file exists.
For example, to assign a static IP to a client, you can add the line
ifconfig-push 10.8.0.50 10.8.0.51(requires IP pair)
Restart the app for changes to take effect.
If you are unable to connect to the OpenVPN server, make sure that your VPS firewall allows the OpenVPN port (by default, this is 7494/TCP). For example, you might have to add this incoming port as part of EC2 security group.
