Technical Questions

What is a VPN?

Virtual private network is a network technology that creates a secure network connection over a public network such as the Internet.

What is encryption in VPN?

Encryption is the process of encoding data so that only a computer with the right decoder will be able to read and use it. In VPN provided by us, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. There are two types of encryption - symmetric and asymmetric.

What is symmetric encryption?

It is the oldest and best-known technique. A secret key, which can be a number, a word, or just a string of random letters, is applied to the text of a message to change the content in a particular way.

What is asymmetric encryption?

Asymmetric encryption (also called public key encryption)is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely.

What is TCP?

TCP (Transmission Control Protocol) is a connection-oriented protocol, which means a connection is established and maintained until the application programs at each end have finished exchanging messages.

What is UDP?

UDP (User Datagram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol

What is IPSec?

Internet Protocol security (IPSec) is a framework of open standards for helping to ensure private, secure communications over Internet Protocol networks through the use of cryptographic security services. IPsec supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data portion (payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encrypts both the header and the payload.

What is PPP?

Point-to-Point Protocol (PPP) is a data link protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption, and compression.

What is PPTP?

PPTP ( Point-to-Point Tunneling Protocol) is a protocol that uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

What is GRE?

Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol internetwork.

What is SSTP?

Secure Socket Tunneling Protocol (SSTP) is a form of VPN tunnel that provides a mechanism to transport PPP or L2TP traffic through an SSL 3.0 channel. SSL provides transport-level security with key-negotiation, encryption and traffic integrity checking. The use of SSL over TCP port 443 allows SSTP to pass through virtually all firewalls and proxy servers except for authenticated web proxies.

What is OpenVPN?

OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.

What is the difference between VPN-connection and Proxy websites?

A Proxy or a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. User connects to the proxy server, requesting some service, such as a file, connection, web page etc. available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. VPN service provider encrypts all of your traffic, replacing your ISP and routing all traffic through the VPN server, including all programs and applications. Hence, for security purposes VPN is the only choice.

Do I need to install software?

You need to install software only when using the OpenVPN. The software is easy to setup. If you encounter any issues, you can always contact our support team: https://boxpn.com/contactus.aspx

Will VPN work over any type of Internet connection?

Yes. Boxpn VPN works over any Internet connection (Cable, DSL, dial up, Satellite, Wi-Fi, etc).
