Hello friends, I hope you all are doing great. In today's tutorial, I am gonna discuss How Point-to-Point Tunneling Protocol (PPTP) Works. Online security is more important than ever. With hackers and brute force attackers, it feels like your private data is constantly at risk. One way to protect your security online is by using a VPN.VPNs may use several protocols. These protocols are like the language that's used by your computer and the VPN server as they communicate. Some protocols are faster than the competition while others prioritize security.One of the oldest, yet still popular, VPN protocols is Point-to-Point Tunneling Protocol, or PPTP. It was introduced in 1995, and though newer protocols have since usurped its place as the greatest, many people and businesses still make use of PPTP.In comparison with newer protocols, PPTP has few data security features. This means that it offers better speeds because it's not bogged down by privacy and security rules. Depending upon how you use PPTP, this relative lack of robust security may serve you well.Privacy Australia illustrates how a VPN protects you with this useful diagram:
How Does PPTP Work?PPTP incorporates factors of the even older Point-to-Point Protocol, or PPP. In this protocol, IP packets of data are encapsulated and transmitted to the VPN server. PPTP creates an encrypted tunnel between the VPN server and the customer's computer via TCP port 1723 as well as General Routing Encapsulation, also called GRE.
- Essentially, this is a client-server setup that utilizes Layer 2 within the OSI model.
