OpenVPN (Virtual Private Network)
Available since: version 0.7
1. What is OpenVPN?
OpenVPN provides to your FreedomBox a virtual private network service. You can use this software for remote access, site-to-site VPNs and Wi-Fi security. OpenVPN includes support for dynamic IP addresses and NAT.
2. Port Forwarding
If your FreedomBox is behind a router, you will need to set up port forwarding on your router. You should forward the following ports for OpenVPN:
- UDP 1194
3. Setting up
In FreedomBox apps menu, select Virtual Private Network (OpenVPN) and click Install.
- After the module is installed, there is an additional setup step that may take a long time to complete. Click "Start setup" to begin.
- Wait for the setup to finish. This could take a while.
Once the setup of the OpenVPN server is complete, you can download your profile. This will download a file called <USER>.ovpn, where <USER> is the name of a FreedomBox user. Each FreedomBox user will be able to download a different profile. Users who are not administrators can download the profile from home page after login.
- The ovpn file contains all the information a vpn client needs to connect to the server.
The downloaded profile contains the domain name of the FreedomBox that the client should connect to. This is picked up from the domain configured in 'Config' section of 'System' page. In case your domain is not configured properly, you may need to change this value after downloading the profile. If your OpenVPN client allows it, you can do this after importing the OpenVPN profile. Otherwise, you can edit the .ovpn profile file in a text editor and change the 'remote' line to contain the WAN IP address or hostname of your FreedomBox as follows.
client remote mybox.freedombox.rocks 1194 proto udp
If your network doesn't support IPv6, you might have to remove the following line from your OpenVPN client configuration. This is especially in cases where your server supports IPv6 but client does not thus confusing the OpenVPN client on which protocol to use.
To connect via IPv4, ensure that the following line is present.
5. Browsing Internet after connecting to VPN
After connecting to the VPN, the client device will be able to browse the Internet without any further configuration. However, a pre-condition for this to work is that you need to have at least one Internet connected network interface which is part of the 'External' firewall zone. Use the networks configuration page to edit the firewall zone for the device's network interfaces.
6.1. On Android/LineageOS
Visit FreedomBox home page. Login with your user account. From home page, download the OpenVPN profile. The file will be named username.ovpn.
Download an OpenVPN client such as OpenVPN for Android. F-Droid repository is recommended. In the app, select import profile.
In the select profile dialog, choose the username.opvn file you have just downloaded. Provide a name for the connection and save the profile.
Newly created profile will show up. If necessary, edit the profile and set the domain name of your FreedomBox as the server address.
- Connect by tapping on the profile.
- When done, disconnect by tapping on the profile.
6.2. On Debian
Install an OpenVPN client for your system
$ sudo apt install openvpn
Open the ovpn file with the OpenVPN client.
$ sudo openvpn --config /path/to/<USER>.ovpn
If you use Network Manager, you can create a new connection by importing the file:
$ sudo apt install network-manager-openvpn-gnome $ sudo nmcli connection import type openvpn file /path/to/<USER>.ovpn
If you get an error such as configuration error: invalid 1th argument to “proto” (line 5) then edit the .ovpn file and remove the line proto udp6.
7. Checking if you are connected
7.1. On Debian
Try to ping the FreedomBox or other devices on the local network.
Running the command ip addr should show a tun0 connection.
The command traceroute freedombox.org should show you the ip address of the VPN server as the first hop.
8. Accessing internal services
After connecting to OpenVPN, you will be able to access FreedomBox services that are only meant to be accessed on internal networks. This is in addition to being able to access external services. This can be done by using the IP address 10.91.0.1 as the host name for these services (for example, use smb://10.91.0.1 instead of smb://freedombox.local to access Samba shares).
The following services are known to work:
Some services are known not to work at this time:
