Three: Create The Client Config
First install Wireguard on your client machine, either the same way on Linux or through an app store if you’re using Windows, macOS, Android, or iPhone.
If you used an online-key-generator or QR script in Step One, then you can connect your phone by taking a picture of the QR code.
Once WireGuard is installed on the client, configure it using these values:
# Replace the PrivateKey value with the one from your client interfaceAddress = 10.0.0.2/24ListenPort = 51820PrivateKey = CNNjIexAmple4A6NMkrDt4iyKeYD1BxSstzer49b8EI=#use the VPN server's PublicKey and the Endpoint IP of the cloud instancePublicKey = WbdIAnOTher1208Uwu9P17ckEYxI1OFAPZ8Ftu9kRQw=AllowedIPs = 0.0.0.0/0Endpoint = 18.104.22.168:51820
There are many optional add-ons that you might want depending on your use-case, such as specifying DNS or pre-shared keys for an extra layer of security.
Start up the client in same way as the server if you are on Linux or through the application itself on other systems.
Reasons Why You Should Not Use A VPN Server
On the flipside, there is always the question of feasibility. Most ISPs serving home users allocate a small upload bandwidth as compared to the download bandwidth. To host a VPN server from home, it is the former i.e. upload bandwidth that primarily matters.
With only a few Mbps of upload bandwidth, youre going to experience extremely slow performance especially if multiple devices are requesting to your VPN server.
Perhaps more importantly, you should first clear any doubts about what you can expect from a home VPN server. One of the main usages of VPNs among consumers is to overcome geo-restrictions and censorship on websites. If all you have is your own home server, then you cant change your virtual location to any other region in order to get past blocked websites.
As such, the VPN server you have running back home is only good if you want to access your private network remotely and you wont have the ability to connect to any other server from any country.
If that is your intent behind creating a VPN server, then you would be better off getting a subscription of a well-reputed and tested VPN provider. Our article on best VPN services for 2022 can help you pick the right VPN for your specific needs.
However, if you just need to establish a private network at home for enhanced encryption and to be able to access it remotely while youre away, then it will be well worth your while to set up you on server.
Including Multiple Machines On The Client Side When Using A Bridged VPN
This requires a more complex setup :
- You must bridge the client TAP interface with the LAN-connected NIC on the client.
- You must manually set the IP/netmask of the TAP interface on the client.
- You must configure client-side machines to use an IP/netmask that is inside of the bridged subnet, possibly by querying a DHCP server on the OpenVPN server side of the VPN.

Generate Server And Client Certificates And Keys
Build a certificate for the VPN server:
Press ENTER to select default answers but pay attention to the last two questions “Sign the certificate? :” and “1 out of 1 certificate requests certified, commit? ” and answer with “y” otherwise the certificate won’t be signed and validated.
Generate Diffie-Hellman parameters:
Warning: Two methods of generating a key will be explained below. Pick just one out of these two. Running both commands would invalidate the certificate.
This key will be imported to the phones/computers that we want to authorize to connect to the OpenVPN server. If you’ll be generating multiple keys for multiple devices, you can choose descriptive names such as “iphone”, “homepc”, “worklaptop” for easier administration later on.
cp keys/server.crt /etc/openvpn/cp keys/server.key /etc/openvpn/cp keys/ca.crt /etc/openvpn/cp keys/dh2048.pem /etc/openvpn/
Use A VPN Router With The Built
As described above, although it is cheaper, turning your own computer into a VPN server can be pretty cumbersome. In that case, another alternative solution is to use a VPN router with an integrated VPN server setup capability. It is good if the router you buy supports a more secure VPN protocol other than PPTP, like the OpenVPN protocol.
However, this can be expensive because if your current router does not have that capability, you may have to buy a new one.
Setting up your VPN router is relatively easy. In summary, the following are the essential steps you need to follow to set up your VPN router as a VPN server.
VPN Router Setup
VPN Client Setup
Once you have enabled VPN in the router, download and unzip the VPN configuration files for the clients from the router control panel, then copy the files to the client devices. Finally, you can connect to the VPN from client devices.

Configure Nat And Enable Pptp
We need to configure Network Address Translation for connected clients to use the Internet. On the left pane of the same routing and remote access window, expand the IPv4 options under your server. Right-click on NAT and select New Interface.
Under the open dialog window, select Public interface and enable NAT on the interface.
Next, navigate to Services and Ports and click VPN Gateway from the drop-down list.
Click Edit to set a Private address for the VPN service, change the current address 0.0.0.0 to 127.0.0.1, and click OK to save.
Finally, click OK to save all changes, then right-click on your server from the left pane and click Restart under the All Tasks sub-menu.
This will restart routing and remote access services making your server ready for incoming VPN connections.
Configuration Of A VPN Server For Interconnecting Networks
In this scenario, two offices in different networks need tobe connected via private network. To do this, you will use Zentyal as agateway in both networks. One will act as a VPN client and the other asa server. The following image clarifies the scenario:
Office interconnection with Zentyal through VPN tunnel
The goal is to connect multiple offices, their Zentyal servers and their internal networks, creating one single network infrastructure in a secure way through the Internet. To do this, you need to configure a VPN server similarly as explained previously.
However, you need to make two small changes. First, enable theAllow Zentyal-to-Zentyal tunnels to exchange routes betweenZentyal servers and then, introduce a Password for Zentyal-to-Zentyal tunnels to establish the connection between the two offices in asafer environment. Take into account that you need to advertise the LAN networks in Advertised Networks.
Another important difference is the routing information exchange. In the Roadwarrior to server scenariodescribed previously, the server pushes network routes to the client. In the Server to server scenario,routes are exchanged in both directions and propagated to other clients using the RIP protocol. Therefore, in the servers that act as VPN clients of the central node, it is also possible to add the Advertised Networks that will be propagated to the other nodes.

Will Your Own VPN Server Be More Secure
Using a private VPN server encrypts the internet traffic between your device and the VPN server. The VPN server also acts as a proxy, thus preventing your internet provider from seeing what you get up to on the internet.
Unlike commercial VPN services, you control the VPN server. This means that you do not have to trust a third party with your data. This is the main reason that running your own VPN server is often recommended for privacy reasons. You can also choose your own VPN server locations.

Option One: Get A Router With VPN Capabilities
Rather than attempting to do this yourself, you can buy a pre-built VPN solution. Higher-end home routers often come with built-in VPN serversjust look for a wireless router that advertises VPN server support. You can then use your routers web interface to activate and configure the VPN server. Be sure to do some research and pick a router that supports the type of VPN you want to use.
How To Set Up A VPN Server In Windows 10
There are many ways to set up a VPN server. Microsofts inbuilt VPN server hosting functionality uses the insecure PPTP protocol, which exposes the computer directly to the internet. In order to avoid this problem, you should use a different port forwarding method or purchase an OpenVPN-compatible router. The next step in setting up a VPN is to configure your network interfaces. This part is a little more complicated, but it can be done!
First, you must make sure that the VPN server is connected to your network. To do this, open your System Preferences, then click the + sign in the left pane. In the Network tab, select the option called VPN. Enter the information required by the VPN provider. If there is any additional information you must provide, you should be prompted. In Windows 10, click on Network and Sharing Center. On the left pane, select Network and Sharing Center. In the right pane, choose Change adapter settings, and then select New Incoming Connection.
Once you have the IP address for the VPN server, configure it with a high-order range. This prevents it from conflicting with the IPs of your router. On your routers DHCP settings page, find the Allow Access option and click it. When you are done, click the Close button to save the settings. To enable your VPN server, you should now be able to connect to the internet from anywhere on the world.

How To Find Your Ip Address Information
The first thing you need to know is the public IP address that has been assigned to you by your Internet Service Provider . You will need this information to contact your VPN server remotely.
To find out your current public IP address, use these steps:
Open your web browser.
Open search an engine like Google or Bing.
Search Whats my IP.
Confirm your public address information in the first result.
Check the public IP address
If you are setting up the Incoming Connection feature in your home computer, you probably have a dynamic public IP address, which can change at any time. If this is the case, you will need to configure DDNS in your router to avoid having to configure the VPN setup every time your public IP address changes.
Here are the instructions that will help you set up DDNS on your router. You can also visit your routers manufacturer website for more assistance to configure DDNS.
What Is A Hosted VPN
This type of VPN exists in response to the need for a more cloud-friendly solution, which suits organizations with many employees working remotely, from several different devices, and connecting to applications and other systems that are held in the cloud and locally.
Hosted VPN providers make it easy and fast to integrate with vital SaaS platforms such as Salesforce, AWS, the Google product suite, and other popular tools.
Even on unsecure public Wi-Fi, a hosted VPN grants users secure access with encrypted tunnels between them and the resources they require to do their jobs.
To navigate their organizations network securely, all employees need to do is login with a web, desktop, or mobile application.

Windows has the built-in ability to function as VPN server using the point-to-point tunneling protocol , although this option is somewhat hidden. Heres how to find it and set up your VPN server.
Setting up a VPN server could be useful for connecting to your home network on the road, playing LAN games with someone, or securing your web browsing on a public Wi-Fi connection a few of the many reasons you might want to use a VPN. This trick works on Windows 7, 8, and 10. The server uses the point-to-point tunneling protocol
Note: Some people who have updated to the Windows 10 Creators Update have a problem where creating a VPN server fails because the Routing and Remote Access Service fails to start. This is a known issue that has not yet been fixed through updates. However, if youre comfortable editing a couple of Registry keys, there is a workaround that seems to fix the problem for most people. Well keep this post up to date if the issue gets formally fixed.

Advantages Of A VPN Connection Via Windows 10
The main advantage of a VPN connection in Windows 10 is privacy. When youre on the road but require access to your business or home network, simply dial into the network via an Internet connection as a VPN client. Unlike external VPN services, your IP remains traceable, but you can access familiar computers or the company network from a distance.
At the same time, you can use your computer as a VPN server and remotely dial into a computer or give other users permission to do so. You can also turn your home router into a VPN server and use it while on the road.
Connecting To A Samba Share Over Openvpn
This example is intended show how OpenVPN clients can connect to a Samba share over a routed dev tun tunnel. If you are ethernet bridging , you probably don’t need to follow these instructions, as OpenVPN clients should see server-side machines in their network neighborhood.
For this example, we will assume that:
- the server-side LAN uses a subnet of 10.66.0.0/24,
- the VPN IP address pool uses 10.8.0.0/24 ,
- the Samba server has an IP address of 10.66.0.4, and
- the Samba server has already been configured and is reachable from the local LAN.
If the Samba and OpenVPN servers are running on different machines, make sure you’ve followed the section on expanding the scope of the VPN to include additional machines.
Next, edit your Samba configuration file . Make sure the hosts allow directive will permit OpenVPN clients coming from the 10.8.0.0/24 subnet to connect. For example:
hosts allow = 10.66.0.0/24 10.8.0.0/24 127.0.0.1
If you are running the Samba and OpenVPN servers on the same machine, you may want to edit the interfaces directive in the smb.conf file to also listen on the TUN interface subnet of 10.8.0.0/24:
interfaces = 10.66.0.0/24 10.8.0.0/24
If you are running the Samba and OpenVPN servers on the same machine, connect from an OpenVPN client to a Samba share using the folder name:
If the Samba and OpenVPN servers are on different machines, use folder name:
For example, from a command prompt window:

Using Alternative Authentication Methods
OpenVPN 2.0 and later include a feature that allows the OpenVPN server to securely obtain a username and password from a connecting client, and to use that information as a basis for authenticating the client.
To use this authentication method, first add the auth-user-pass directive to the client configuration. It will direct the OpenVPN client to query the user for a username/password, passing it on to the server over the secure TLS channel.
Next, configure the server to use an authentication plugin, which may be a script, shared object, or DLL. The OpenVPN server will call the plugin every time a VPN client tries to connect, passing it the username/password entered on the client. The authentication plugin can control whether or not the OpenVPN server allows the client to connect by returning a failure or success value.
