- OpenVPN 2.5.8 Server is fully compatible
- Compatible OpenVPN Server images can be found on Docker Hub - d3vilh/openvpn-server:latest
- As well as Openvpn-UI itself - d3vilh/openvpn-ui:latest
- Support any architecture, ready images for AMD64 and ARM available on Docker Hub.
Part of following projects:
- Openvpn-aws OpenVPN and OpenVPN-UI for any Cloud, VM or x86 bare metal server.
- Raspberry-gateway simple yet powerful home gateway environment with Pi-Hole +Unbound, VPN, Torrent client and Internet monitoring, all managed by Portainer.
Installation
For the best experience, it is recommended to deploy it within a Docker environment consisting of two distinct containers:
- The
d3vilh/openvpn-server
Back-End container (openvpn) for running OpenVPN server. - OpenVPN UI Front-End container (openvpn-ui) for efficient management of the OpenVPN server environment.
However it works fine as standalone application with standalove OpenVPN server as well.
Intel x86 and AMD64 platforms
You can run both containers from the official openvpn-server repository, docker-compose-openvpnui.yml
.
It includes all the files in its main directory.
For automated installation on baremetal x86-64 servers, Cloud or VM installation, please use openvpn-aws project. It, as well, includes all the necessary scripts for easy installation of OpenVPN-UI and OpenVPN server on any x86-64 platform.
Raspberry-pi and other ARM platforms
For Raspberry-Pi and other ARM devices, consider Raspberry-Gateway project. It has all the necessary scripts for easy installation and lot of additional features.
You can run both containers from the openvpn-server repository as well (use docker-compose-openvpnui.yml
).
It includes all the files in its main directory, as well.
Manual installation

Building own image
Building own image
Prerequisites
As prerequisite, you need to have Docker and GoLang to be installed and running:
sudo apt-get install docker.io -y
sudo systemctl restart docker
To install Golang go to https://go.dev/dl and copy download URL for Go1.20.X version of your arch and follow the instructions below.
Example for ARM64:
wget https://golang.org/dl/go1.20.linux-arm64.tar.gz
sudo tar -C /usr/local -xzf go1.20.linux-arm64.tar.gz
echo "export PATH=$PATH:/usr/local/go/bin" >> /etc/profile
source /etc/profile
go version
Building the image
To build the OpenVPN-UI image:
cd build; ./build_openvpn-ui.sh
The new image will have openvpn-ui
name.
Upgrade to new Version
During the installtion or upgrade process OpenVPN-UI by itself does not do any changes to your OpenVPN server configuration or PKI infrastructure. However it is recommended to perform backup of your PKI infrastructure
, server.conf
, client.conf
and data.db
before following with upgrade steps.
Backup
Backup
To backup your PKI infrastructure, server, client configuration files and OpenVPN-UI DB you can use backup.sh
script which is in build/assets
directory (since the release 0.6
), it is also part of openvpn-aws and Raspberry-Gateway projects (right in openvpn-server directory).
Copy the script in your home directory(any directory in fact):
cp -p build/assets/backup.sh ~/
Then run the script:
sudo ./backup.sh -b ~/openvpn-server backup/openvpn-server-030923-1
this will create backup of all necessary files, from ~/openvpn-server
to ~/backup/openvpn-server-030923-1
.
You can confirm all files are backed up and go to the "Upgrade" step.
Upgrade
Upgrade
To upgrade OpenVPN-UI to the latest version, you have to save old container image, remove old container and deploy new container with upgraded image.
Preparation
- Check which OpenVPN-UI version image is currently used:
docker inspect --format='{{json .Config.Labels}}' d3vilh/openvpn-ui:latest
{"maintainer":"Mr.Philipp <d3vilh@github.com>","version":"0.5"}
Note: Old container versions (below ver 0.5) does not have "version" tag.
- Tag current container image with backup tag:
docker tag d3vilh/openvpn-ui:latest local/openvpn-ui:backup
- Make sure your docker-compose.yml file is up to date with desired new version of image. Our assumption that desired is the
latest
version:
admin@aws3:~/openvpn $ cat docker-compose.yml | grep image
image: d3vilh/openvpn-ui:latest
admin@aws3:~/openvpn $
During the next container start, docker will use image tag from this file to deploy new container.
Upgrade Steps
- Pull new image to your host. Old image will be replaced:
docker pull d3vilh/openvpn-ui:latest
- Confirm new image is pulled with desired version:
docker inspect --format='{{json .Config.Labels}}' d3vilh/openvpn-ui:latest
{"maintainer":"Mr.Philipp <d3vilh@github.com>","version":"0.9.4"}
- Stop and remove old container:
docker rm openvpn-ui --force
- Deploy new container with updated image:
cd ~/openvpn-server
docker-compose up -d
- Verify both containers are up and running:
admin@aws3:~/openvpn $ docker logs openvpn-ui
...
2023/09/03 12:38:50.650 [I] [server.go:280] http server Running on http://:8080
admin@aws3:~/openvpn $
admin@aws3:~/openvpn $ docker logs openvpn
...
Start openvpn process...
admin@aws3:~/openvpn $
Verification process
Now when new OpenVPN-UI version is deployed, the DB schema were updated to the latest version automatically during the container start.
- All tables were updated with new fields, existed fields in those tables were not touched to be sure you won't loose any data.
- New tables were created with default values.
Now you need to go to Configuration > OpenVPN Server
in OpenVPN UI webpage and review and update all options fields very carefully.
Here is example of Server configuration page with new fields after the upgrade from version 0.3 to 0.9:
You have to update empty fields with options from your current server.conf
and only then press Save Config
button.
All fields to review are marked with ! sign:
Here is how it should looks like:
Important Note!: In version 0.6 format of some fields has been changed! Please pay attention that before saving config you have to update all the fields with new format, otherwise OpenVPN Server will not start.
New server.conf
file will be applied immedeately, after you press Save Config
button.
Next, you have to update OpenVPN UI
, OpenVPN Client
and EasyRSA vars
pages the same way.
And you are done with the upgrade process.

Fallback
Fallback
If for some reason you would like to fallback to the previous version, you need to stop container, restore image, then restore all the files from backup you did before and finally run container with previous image.
Container and image fallback
- Stop and remove updated openvpn-ui container:
docker rm openvpn-ui --force
- Remove updated openvpn-ui image:
docker image rm d3vilh/openvpn-ui:latest
- Restore old openvpn-ui image:
docker tag local/openvpn-ui:backup d3vilh/openvpn-ui:latest
- Confirm you have old image version:
docker inspect --format='{{json .Config.Labels}}' d3vilh/openvpn-ui:latest
{"maintainer":"Mr.Philipp <d3vilh@github.com>","version":"0.5"}
Restore OpenVPN Server enviroment
- Run restore script:
sudo ./backup.sh -r ~/openvpn-server backup/openvpn-server-030923-1
This will restore all the enviroment files from backup directory to ~/openvpn-server
directory.
Note v.0.3: There was bug in version 0.3 where data.db file were not shared over the volume, so you have to restore it manually:
docker cp backup/data.0.3.db openvpn-ui:/opt/openvpn-ui/data.db
Restore container
- Run docker-compose up to deploy new container with old image:
cd ~/openvpn-server
docker-compose up -d
- Verify both containers are up and running:
admin@aws3:~/openvpn $ docker logs openvpn-ui
...
2023/09/03 12:38:50.650 [I] [server.go:280] http server Running on http://:8080
admin@aws3:~/openvpn $
admin@aws3:~/openvpn $ docker logs openvpn
...
Start openvpn process...
admin@aws3:~/openvpn $
Thats it you are back to the previous version.
Configuration
OpenVPN UI can be accessed on own port (*e.g. http://localhost:8080), the default user and password is admin/gagaZush
preconfigured in config.yml
if you are using Raspberry-Gateway or Openvpn-aws projects. For standalone installation, you can pass your own credentials via environment variables to container (refer to Manual installation).
Container volume
The container volume can be initialized by using the d3vilh/openvpn-server image with included scripts to automatically generate everything you need on the first run:
- Diffie-Hellman parameters
- an EasyRSA CA key and certificate
- a new private key
- a self-certificate matching the private key for the OpenVPN server
- a TLS auth key from HMAC security
However you can generate all the above components on OpenVPN UI Configuration > Maintenance
page.
EasyRSA vars
You can update all EasyRSA parameters with OpenVPN UI on Configuration > EasyRSA vars
page. You also can set custom EasyRSA vars for every new Client Certificate during its creation.
If you are running OpenVPN-UI as manuall installation, please be sure easy-rsa.vars
is set properly and placed in .config
container volume as easy-rsa.vars
.
In this case your custom EasyRSA options will be applied on the first OpenVPN Server start post PKI init step.
Default EasyRSA configuration can be set in ~/openvpn-server/config/easy-rsa.vars
file:
set_var EASYRSA_DN "org"
set_var EASYRSA_REQ_COUNTRY "UA"
set_var EASYRSA_REQ_PROVINCE "KY"
set_var EASYRSA_REQ_CITY "Kyiv"
set_var EASYRSA_REQ_ORG "SweetHome"
set_var EASYRSA_REQ_EMAIL "sweet@home.net"
set_var EASYRSA_REQ_OU "MyOrganizationalUnit"
set_var EASYRSA_REQ_CN "server"
set_var EASYRSA_KEY_SIZE 2048
set_var EASYRSA_CA_EXPIRE 3650
set_var EASYRSA_CERT_EXPIRE 825
set_var EASYRSA_CERT_RENEW 30
set_var EASYRSA_CRL_DAYS 180
In the process of installation these vars will be copied to container volume /etc/openvpn/pki/vars
and used during all EasyRSA operations.
Network configuration
This setup use tun
mode by default, because it works on the widest range of devices. tap
mode, for instance, does not work on Android, except if the device is rooted.
The default topology is subnet
, because it works on the widest range of OS. p2p
, for instance, does not work on Windows.
The server config by default specifies push redirect-gateway def1 bypass-dhcp
, meaning that after establishing the VPN connection, all traffic will go through the VPN. This might cause problems if you use local DNS recursors which are not directly reachable, since you will try to reach them through the VPN and they might not answer to you. If that happens, use public DNS resolvers like those of OpenDNS (208.67.222.222
and 208.67.220.220
) or Google (8.8.4.4
and 8.8.8.8
).
If you wish to use your local DNS server (Pi-Hile?), you have to modify a dns-configuration with your local DNS IP address.
This also can be done easy via "Configuration" > "OpenVPN Server" > "Push DHCP"
options on OpenVPN UI webpage.
OpenVPN client subnets. Guest and Home users
By default d3vilh/openvpn-server OpenVPN server uses option server 10.0.70.0/24
as "Trusted" subnet to grab dynamic IPs for all your Clients which, by default will have full access to your "Private/Home" subnet, as well as Internet over VPN.
However you can be desired to share internet over VPN with specific, Guest Clients and restrict access to your "Private/Home" subnet. For this scenario d3vilh/openvpn-server server.conf
configuration file has special route 10.0.71.0/24
option, aka "Guest users" subnet.
To assign desired subnet policy to the specific client, you have to define static IP address for the client during its profile/Certificate creation.
To do that, just enter "Static IP (optional)"
field in "Certificates"
page and press "Create"
button.
Keep in mind, by default, all the clients have full access, so you don't need to specifically configure static IP for your own devices, your home devices always will land to "Trusted" subnet by default.
Firewall rules
By default docker_entrypoint.sh
of d3vilh/openvpn-server OpenVPN Server container will apply following Firewall rules:
IPT MASQ Chains:
MASQUERADE all -- ip-10-0-70-0.ec2.internal/24 anywhere
MASQUERADE all -- ip-10-0-71-0.ec2.internal/24 anywhere
IPT FWD Chains:
0 0 DROP 1 -- * * 10.0.71.0/24 0.0.0.0/0 icmptype 8
0 0 DROP 1 -- * * 10.0.71.0/24 0.0.0.0/0 icmptype 0
0 0 DROP 0 -- * * 10.0.71.0/24 192.168.88.0/24
You can apply optional Firewall rules in ~/openvpn-server/fw-rules.sh
file, which will be executed on the container start.
Here is example of blocking all the traffic between 2 "Trusted" subnet clients:
~/openvpn-server $ cat fw-rules.sh
iptables -A FORWARD -s 10.0.70.88 -d 10.0.70.77 -j DROP
iptables -A FORWARD -d 10.0.70.77 -s 10.0.70.88 -j DROP
Check detailed subnets description on here.

Generating .OVPN client profiles
How to generate .OVPN client profile
You can update external client IP and port address anytime under `"Configuration > OpenVPN Client"` menue.For this go to "Configuration > OpenVPN Client"
:
And then update "Connection Address"
and "Connection Port"
fields with your external Internet IP and Port.
To generate new Client Certificate go to "Certificates"
, then press "Create Certificate"
button, enter new VPN client name, complete all the rest fields and press "Create"
to generate new Client certificate:
To download .OVPN client configuration file, press on the Client Name
you just created:
Install Official OpenVPN client to your client device.
Deliver .OVPN profile to the client device and import it as a FILE, then connect with new profile to enjoy your free VPN:
Renew Certificates for client profiles
How to renew old client profile
To renew certificate, go to `"Certificates"` and press `"Renew"` button for the client you would like to renew certificate for:Right after this step new Certificate will be genrated and it will appear as new client profile with the same Client name. At this point both client profiles will have updated Certificate when you try to download it.
Once you will deliver new client profile with renewed Certificate to you client, press "Revoke"
button for old profile to revoke old Certificate, old client profile will be deleted from the list.
If, for some reason you still would like to keep old certificate you have to "Revoke"
new profile, old certificate will be rolled back and new profile will be deleted from the list.
Renewal process will not affect active VPN connections, old client will be disconnected only after you revoke old certificate or certificate term of use will expire.
Revoking .OVPN profiles
How to revoke client certificate
If you would like to prevent client to use yor VPN connection, you have to revoke client certificate and restart the OpenVPN daemon.
You can do it via OpenVPN UI "Certificates"
menue, by pressing `"Revoke"`` amber button:
Certificate revoke won't kill active VPN connections, you'll have to restart the service if you want the user to immediately disconnect. It can be done from the same "Certificates"
page, by pressing Restart red button:
You can do the same from the "Maintenance"
page.
After Revoking and Restarting the service, the client will be disconnected and will not be able to connect again with the same certificate. To delete the certificate from the server, you have to press "Remove"
button.
Two Factor Authentication (2FA)
Starting from vestion 0.9.3
OpenVPN-UI has Two Factor Authentication (2FA) feature.
OpenVPN-UI uses oath-toolkit for two factor authentication. Means you don't need any ThirdParty 2FA provider.
When generating 2FA-enabled certificates OpenVPN-UI will provide QR code with 2FA secret, which you can scan with your 2FA app (Google Authenticator iOS, Android, Microsoft Authenticator iOS, Android, etc) to get 2FA token for connection with this certificate.
2FA Certificates Renewal
, Revoke
and Delete
process is the same as for regular certificates.
To enable 2FA you have to:
-
Go to
"Configuration > OpenVPN Client"
page and enable"Two Factor Authentication"
option to switch Certificates interface to 2FA mode, so you can generate certificates with 2FA enabled and access 2FA QR code for already generated certificates.Note: You can generate 2FA-ready certificates at this stage, then deliver 2FA Certificates to all your client devices and enable 2FA Server support later, when you'll be ready to use it. Before that Server will still accept non 2FA-ready certificates only.
-
Go to
"Configuration > OpenVPN Server"
page and enable"Two Factor Authentication"
option for OpenVPN Server backend. Once 2FA is enabled for Server, OpenVPN-Server will allow 2FA connections only (non 2FA-ready certificates won't connect).
2FA .OVPN profiles creation
How to generate 2FA Certificate
Procedure for 2FA generation is the same as for regular certificate, but you have to use the uniq 2FA Name
in the email-kind format:
Note: For Multifactor Authentication (MFA), you can add one more password by completing
Passphrase
option.
Both Passphrase
and Client Static IP
are optional parameters.
When you complete all the fields, click on Create
and your new 2FA Certificate will be ready.
Once this done, you can click on the new certificate in the Certificates
page to see all the details including QR code for 2FA token:
You can copy or email this information directly to happy 2FA certificate owner.

To use 2FA certificate you have to install 2FA app on your device (Google Authenticator iOS, Android, Microsoft Authenticator iOS, Android, etc) and scan QR code from the Certificates
details page.
After scanning QR-code, new Authenticator profile will be created in your 2FA app with the same name as your 2FA Certificate name:
Then you have to download and deliver .OVPN profile
to OpenVPN Connect app and open it as a file. Following window appear:
Click Add
to add new profile to OpenVPN Connect. Then you will be asked to enter your Username. As username use 2FA Name
which you used during Certificate/profile generation (as precisely as you can. 2FA Name
is part of authentication process):
When you'll be prompted to Enter the password, you have to enter your 2FA token from your 2FA app:
Connection will be suceeded if you entered 2FA Name
and 2FA token correctly.
For MFA authentication you can use optional Passphrase
when generating new Client certificate, to protect your 2FA token with additional password. In this case you have to enter your Passphrase
as a Private Key Password
and 2FA token as Password
