Pros and Cons of Open VPN Technology

OpenVPN

If you want to browse the Internet anonymously and simply being secured online, VPN (Virtual Private Network) is without a doubt the best choice. As compared to other methods, VPN offers encrypted web traffic which protects you from undesirable third party. However, there are many types of VPN, and Open VPN is only one of them.

In layman’s term, Open VPN is an open source software application that provides secured virtual connection between two computers at different locations. To achieve secured connection, it uses the OpenSSL encryption library along with other strong security features. Despite being fairly new, it is one of the most preferred VPN protocol.

But before you decide to use it to secure your Internet connection, below are some of the major advantages and disadvantages of Open VPN.

 pros-and-cons

Pros of Open VPN:

 Strong encryption

Open VPN is known for having a strong encryption, which is considerably better against the NSA (National Security Agency). The OpenSSL encryption library supports a number of cryptographic algorithms including the AES which is known for almost no weakness at all.

 Highly reliable

 Besides being secured, Open VPN is highly reliable, thanks to its capability of allowing for repair or reconfiguration even if the network is down. This means that no drop of packets which means no data will be lost once there is a corruption during the communication.

Works with DD-WRT routers

 This is a great advantage if you want to run your local network on a single VPN account. To be able to achieve this, you will need a DD-WRT supporting router. Thiif done correctly, this free Linux-based firmware upgrade allows you to share a single VPN connection.

 Great community support

 This is pretty obvious because of the extreme popularity of Open VPN. And because it is an open source application, it can be easily be modified. This is why you can easily get support from other users around the globe. And yes, it is very much applicable to mobile phones.

We can recommend a great Open VPN for Android – Spider VPN.

 Cons of Open VPN

 Software required

You will need third party software before you can use Open VPN. You will need it for the authentication of the VPN server. If you are not a techie guy, this might be a problem to you. Although it is pretty easy to install, you might find it complicated to use if you are a beginner.

Possibility of High Latency

In terms of Internet, latency is the time delay of the response in the network, and is therefore a waste of time and can be annoying if you playing online games. And because of the high load in Open VPN, you might encounter this problem depending on your location of your access.

There are other disadvantages of Open VPN, but they are considerably minor. For example, it is quite slower than PPTP (Point-to-Point Tunneling Protocol) and L2TP/IPSec. Some user also note that Open VPN for desktop computers is better than for mobile devices. However, if you are really concern with security and reliability, then you should choose Open VPN.

5 Advantages of OpenVPN (Spider VPN)

Advantages of Open VPN

VPN (Virtual Private Network) has been proven to be the best way to browse the web anonymously. Besides being flexible, it is by far more secured than other similar technologies. With VPN, web traffic is encrypted which means no third party can easily intercept your data. Mobile users are protected when they are in a public Wi-Fi zone or a in a country with strict Internet policies. VPN offers different security protocols to choose from, and Open VPN is one of them. Here are some of its notable advantages:

1. Very easy to install and use

Released in 2002, this OpenVPN open-source software is very easy install and use. You can install it on a server and client on any platform (such as Linux, Windows, Mac OS X, and others) without restrictions. OpenVPN server waits until a client submits a request for connection, and the client establishes the connection according to the given configuration. Despite requiring you to download and setup additional configuration files, it does not come as a burden as there are tons of tutorials available.

2. Offers high level of security

OpenVPN offers various security features as such as peer authentication, digital certifications, and very strong encryption standards. It uses security protocols from the OpenSSL encryption library and SSL v3/TLS v1 protocol. The cryptographic algorithms (e.g. AES, Blowfish, 3DES, CAST-128, etc) being used are known to have no serious security issues from any party, including the NSA (National Security Agency). The 128-bit Blowfish is OpenVPN’s default cipher, but the newer AES provides more security.

 3. Highly configurable and flexible

 OpenVPN is highly configurable as compared to other security protocols. It can be set to run on any port, but is known to run best at TCP port 443. This makes OpenVPN traffic harder to distinguish and block as compared to the traffic from the HTTPS websites. During connection set up, OpenVPN also offers numerous points making it very flexible to all kinds of users. Connections can be tunneled through almost every available proxy and firewall, thus providing additional protection for field workers.

4. Great community support

OpenVPN requires you to download a third party app, but support from the community is great. Due to its popularity, it has already acquired a huge amount of fans all over the world. Not to mention, OpenVPN network can be connected on mobile devices and works well on various operating software such as Apple’s iOS and Android. And because it is an open source, source code is readily available and is free for modification. In short, receiving support is never a problem for OpenVPN users.

 5. Highly reliable

With OpenVPN, there is no data loss even if the system goes down. Instead, the network stops so that repair and reconfiguration can be done immediately. This feature also serves as an additional security measure. OpenVPN is also considered as the most stable and reliable VPN protocol on wireless routers, non-reliable networks, as well as on Wi-Fi zones. When it comes to speed, it is notably fast even on far distances and connections with high latency. This is why many VPN providers are offering it.

How to Access Blocked Websites in China

Last Update: June 12 2016.

The Great Firewall of China has been blocking more than 2,700 websites for years, and they are still continuously adding more blocked websites. The list of banned websites in China includes Google, YouTube, tons of Wikipedia pages, Facebook, LinkedIn, and Twitter. Skype a is allowed in China, but its version is different from the international version. Line and many others popular VOIP services are blocked in the country. As of 2013, the more than two million people have been closely monitoring Internet activities. This is why you should choose a very reliable VPN service.

Generally speaking, a VPN (Virtual Private Network) allows you to bypass any kind of Internet firewalls including China’s Great Firewall. This means you can easily have access to any website you want. While there are other ways to unblock restricted sites in China, VPN is considered the best option. With VPN for China, your online activities are encrypted so almost no one can intercept them. The level of security you can enjoy depends on the VPN you need. But obviously, you need to pay more for a higher level.

China has no laws against VPNs, but they have blocked a lot of websites of VPN service providers. OpenVPN, which allows users to different ports for bypassing firewalls, was blocked in China sometime between 2011 and 2012. There are also VPNs that are being partially blocked by the Chinese government. For this reason, you should be very careful in choosing a VPN service provider. But again, VPN remains to be far more reliable way to surf the Internet anonymously as compared to the others.

You should also understand that the Great Firewall of China is constantly being updated, which means China gets stricter as time passes by. So, if your traffic is not encrypted the way VPN does, you will only waste your time and money. Apparently, there are also free VPNs and you can also use them. But for obvious reasons, you don’t expect a free service winning against China’s very strict policies. You will also encounter tons of advertisements simply because it needs money for its operational expenses.

So, if you really want to have an access to blocked sites in China, you have to invest money. After all, there are many paid VPNs that offer very affordable service fees but can meet your requirements. The key here is to know first what you really need in a VPN. What websites do you want to visit? Are you going to visit them frequently? Will you also watch videos? Will you use it for your personal needs only? If have a business, will you allow your employees use VPN too? How much is your budget?

When choosing a VPN for China, make sure it can provide immediate customer support. To reduce downtime, choose also the one that can instantly provide you a new IP address in case the first one was blocked. These days, VPNs are already applicable to smartphones. But some of them only work well for iOs but not for Android. So, make sure your VPN has been tested for all operating software. Lastly, your VPN provider should always make regular updates and does not keep users’ log details.
