The Predecessors Of The VPN
Their efforts led to the creation of ARPANET , a packet switching network, which in turn led to the development of the Transfer Control Protocol/Internet Protocol .
The TCP/IP had four levels: Link, internet, transport and application. At the internet level, local networks and devices could be connected to the universal network and this is where the risk of exposure became clear. In 1993, a team from Columbia University and AT&T Bell Labs finally succeeded in creating a kind of first version of the modern VPN, known as swIPe: Software IP encryption protocol.
In the following year, Wei Xu developed the IPSec network, an internet security protocol that authenticates and encrypts information packets shared online. In 1996, a Microsoft employee named Gurdeep Singh-Pall created a Peer-to-Peer Tunneling Protocol .
What Is A VPN
VPN stands for virtual private network. With a VPN connection, which securely connects your remote device to your office network, you can access your office network just as if you were in the building. Because the connection is encrypted, you do not need to worry about others snooping around your connection as you would with a public Wi-Fi connection. Think of the connection between your remote computer and your network as being a private pipeline.

Payment Plan And Affordability
Managing a non-profit organization means you have to be very careful with how you spend your resources. This is why affordability is a very important factor in selecting the right VPN to connect to your work computer from home to access files remotely.
While VPNs are generally affordable, the price may be a concern if you are on a tight budget. Luckily, there are a lot of VPN providers in the market and you will find one in your desired budget.

What Are The Benefits Of A VPN
What can you do with a VPN? In a nutshell, youre able to secure your online presence, but exactly what does that mean?
- VPNs help bypass censorship censorship is a common problem. Some sites are banned depending on where you are, and the only way you can access them is with a VPN. Did you know, for example, that there are certain video games you cannot access from countries like Australia and the UK because they are considered too violent or overtly sexual? A VPN helps you get around the problem. In countries like Russia and China where censorship is more widespread and affects news sites and social media websites VPNs provide a secure means to go online.
- Streaming this is one of the most common reasons why people buy VPNs. Streaming platforms restrict content depending on the region. You may have a Netflix subscription but that doesnt mean you have access to all their content; you can only watch what they have licensed for your country. Streaming with a VPN gives you online privacy and allows you to log in through a remote server where the content you want to watch is licensed.

Types Of VPN Security Protocols
To understand what is a VPN and how does it work, you need to know a little about protocols. There are many types of VPN protocols, but there are few that really matter:
- OpenVPN this is a popular, open-source protocol that deals mainly with encryption. It ensures that your data is securely encrypted and then decrypts it in the correct order. It does all this while ensuring that the encryption and decryption processes dont slow down your speeds.
- IPSec/IKEv2 this protocol deals with establishing authenticated encryption connections. It also keeps encryption stable if a user switches between connections. So, if you switch from Wi-Fi to mobile, for example, this protocol ensures that your data doesnt leak.
- L2TP/IPSec this provides a tunnel between your device and the VPN server. Once in the tunnel, other protocols take over to keep the data secure.
- PPTP this was the first commonly used VPN protocol. Because it is fast it is a recommended protocol for VPNs for streaming.
Youll find that the best VPNs use a combination of several protocols that do different things to provide secure connections.
Some VPNs use additional protocols like WireGuard and Chameleon to provide extra security and peace of mind.
If Youre Running Tomato Firmware
Open up your browser and enter in your routers IP address. We assume that if you installed Tomato, you know the IP address of your router. If youre not sure, then its probably set to the default of 192.168.1.1. After, type in your username and password.
Although its not required, you may want to backup your current Tomato configuration before upgrading to TomatoUSB VPN, just in case. To save your configuration, navigate to Administration > Configuration and click the Backup button. This will prompt you to save the .cfg file to your computer.
Now its time to upgrade Tomato to TomatoUSB VPN. Click Upgrade in the left column and click the Choose File button. Navigate to the files we extracted earlier and choose the tomato-NDUSB-1.28.8754-vpn3.6.trx file. Then click the upgrade button.
Youll be asked to confirm the upgrade; just click OK.
Your router will begin uploading the new firmware and will restart within a minute.

Access Files Through VPN On The Host Pc
Now, you should be able to access files through a VPN on Windows 10, together with printers. However, if it doesnt work, make sure that Network Discovery isnt disabled on the host PC.
For quick file access, you can map network drives through a VPN. Besides accessing files through the VPN using a file browser, you can also use an FTP client if the host PC is configured to run an FTP server.
An alternative solution is to use remote control software to access files on a computer in a different network.
Work From Home During Covid
VPN is especially helpful during the current times when nearly every business is working from home in the wake of the COVID-19 pandemic. The key to an efficient operation during this unprecedented time is constant communication between team members. Its why video-conferencing services have seen a significant jump in new users.
In the professional space, a company has a local network that includes computers and other devices such as printers. Usually, a filesharing folder is also present to allow different teams to share files swiftly. VPN allows the employees to continue to access such resources when they are working from home by connecting to the companys VPN. This VPN is very private, and grants access through credentials provided by the company.

Where The Trouble Begins
At this point every is working fine. From your laptop, you can access the office resources, remote into your PC, etc. When you open a web browser you can go anywhere you wish, just as you could before you established the office VPN connection. However, you may notice the network is running more slowly when the VPN is active.
The reason for this is simple. Now all the network traffic is running through the office VPN connection. For example, lets say you want to watch some screaming goat videos on YouTube . The request and information goes from your laptop at home, through the VPN to the office router, then back out to the Internet, and finally to YouTube. The reply back from YouTube follows the same path back. No wonder your network seems so slow.
If your office is in a very large company that has a dedicated connection with symmetric upload/download speeds at 1 GHz, then there may not be much of a speed issue . However, if your office is like most companies and has a significantly less expensive asymmetric service, the difference is significant. The table below shows typical speeds available to a business. All numbers are specified in Mbps.

Advantage : Fight Online Censorship
In a lot of countries governments heavily censor the internet. These countries block access to certain internet services and websites. Examples of apps and websites that are often blocked are WhatsApp, Google, Instagram, YouTube, Skype, Spotify and Facebook. Moreover, news websites and journalist platforms are often blocked because they are seen as a threat to the sitting government. In these countries this censorship heavily impacts the freedom of speech of their citizens.
In some western countries there are also online restrictions.; For example, many countries block the Pirate Bay website because they do not want their citizens to download illegal materials.
A VPN can help you bypass censorship and restrictions by allowing you to connect to a server in a different country. By doing this you can go online as if you were in that other country. This way you can gain access to websites and services that are not available in your own country.

How Does A VPN Work
A VPN hides your IP address by letting the network redirect it through a specially configured remote server run by a VPN host. This means that if you surf online with a VPN, the VPN server becomes the source of your data. This means your Internet Service Provider and other third parties cannot see which websites you visit or what data you send and receive online. A VPN works like a filter that turns all your data into “gibberish”. Even if someone were to get their hands on your data, it would be useless.
How To Login Into VPN
VPN is a service which allows a remote user to create a secure tunnel into the IAS network over a non-IAS Internet service provider. Once authenticated the user is then able to gain access to IAS-restricted resources.
VPN is especially useful for IAS faculty, members, and staff that may be accessing the campus network using a commercial Internet Service Provider and wish to gain access to IAS-only resources . When you authenticate to the VPN server, your computer is assigned a second IP address from the pool of IAS-specific IP addresses. Once you have this second IP address, it is as if you are using the network from a machine on campus .

Things You Need If You Want To Set Up A VPN In Windows 10
To be able to connect to a Virtual Private Network , regardless of whether it is owned by the company you work for or if it is a custom connection that you have set up, you have to know the following details:
- The IP address of the VPN server to which you are going to connect;
- The connection name and your VPN account details: username and password;
- Any custom configuration you might need to perform to establish a secure connection to that VPN.
If you have all these particular details, the only other thing you need is a functioning internet connection. Just pointing out the obvious, it is impossible to connect to a VPN server if you are not already connected to the internet. If you managed to gather all the proper credentials, feel free to continue on your journey towards using a VPN service with this guide’s help. Let’s see how to create and configure a VPN connection in Windows 10:
Creating The Certificates And Keys
In the command prompt, type cd c:\Program Files \OpenVPN\easy-rsa if youre running 64-bit Windows 7 as seen below. Type cd c:\Program Files\OpenVPN\easy-rsa if youre running 32-bit Windows 7. Then hit Enter.
Now type init-config and hit Enter to copy two files called vars.bat and openssl.cnf into the easy-rsa folder. Keep your command prompt up as well be coming back to it shortly.
Navigate to C:\Program Files \OpenVPN\easy-rsa and right click on the file called vars.bat. Click Edit to open it up in Notepad. Alternatively, we recommend opening this file with Notepad++ as it formats the text in the file much better. You can download Notepad++ from their homepage.
The bottom portion of the file is what we are concerned with. Starting at line 31, change the KEY_COUNTRY value, KEY_PROVINCE value, etc. to your country, province, etc. For example, we changed our province to IL, city to Chicago, org to HowToGeek, and email to our own email address. Also, if youre running Windows 7 64-bit, change the HOME value in line 6 to %ProgramFiles %\OpenVPN\easy-rsa. Do not change this value if youre running 32-bit Windows 7. Your file should look similar to ours below . Save the file by overwriting it once youre done editing.
Go back to your command prompt and type vars and hit Enter. Then type clean-all and hit Enter. Finally, type build-ca and hit Enter.
In the same command prompt type build-dh. This command will output one file in the easy-rsa/keys folder.

A Note About Routers And Pptp
Most routers support PPTP connections, which is also the protocol used in our example above. However, many security experts consider PPTP to be obsolete due to the low safety level it provides. It can be easily hacked.
A safer solution is to get a VPN router that supports VPN client connections. If the router has customizable firmware, then you can remove the stock firmware to replace it with DD-WRT, Tomato, or OpenWRT.
Were talking about the best router firmware for Windows 10, which is open-source and allows OpenVPN configurations. Using OpenVPN to remotely connect to another PC and gain file access is significantly more secure than using PPTP or L2TP.
Using OpenVPN in a manual configuration way is also the only way to set up a VPN for Amazon Echo and Alexa.
