AMANVPN uses different VPN protocols to establish VPN connections. This article will help you further understand the protocols we use.

What is the VPN protocol?

The VPN protocol means that the VPN provides commercial services for the VPN to achieve stable and secure instructions for the communication between the VPN server and the VPN server. It depends on how your data is transmitted in the VPN tunnel. You can encrypt your Internet communications in various ways. Each VPN protocol has its own specifications, which can be chosen by you.

VPN protocol type.

• Open VPN.

OpenVPN is an open source commercial software that supports multiple authentication methods. The project implements virtual private network (VPN) technology to establish secure point-to-point or website-to-site connections in routing or bridging configurations and remote access devices. Use custom security protocol, use SSL/TLS for key exchange. The OpenVPN protocol in the AMANVPN app uses 53.123.443.1194 and 8293 for its Android and macOS apps, and port 1195 in the Windows app. OpenVPN is the first choice for those who care about performance and security.

• IKEv2

Internet Key Exchange Version 2 (IKEv2) is a protocol used to process requests and response encryption. This is a stable and secure agreement, and it is easy to establish. Compared with traditional VPN protocols, such as L2TP, IKEv2 is more stable, safer and faster. IKEv2 runs on UDP port 500.

• L2TP

The second layer of L2TP (L2TP) tunneling protocol relies on an encryption protocol that provides anonymity through the tunnel. In order to protect the data load, it is usually paired with IPSec. L2TP requires UDP ports 500.1701 and 4500 and IP-ESP protocol IP protocol 50.

• PPTP

PPTP stands for Peer-to-Peer Tunneling Protocol. PPTP runs on TCP port 1723, which is one of the VPN protocols still in use today.

PPTP is the most commonly used among all VPN protocols, and it is also the easiest to set up and the fastest to calculate. Because of this, PPTP is very important for speed applications, such as audio or video streaming, as well as on older slower processors.

However, PPTP also has serious security vulnerabilities. The underlying authentication protocol, usually MS-CHAP-v1/v2, is a fundamentally insecure authentication protocol. Since PPTP came out, it has been cracked many times.

Therefore, it is recommended not to use PPTP, except when safety is absolutely irrelevant.

• V2Ray

V2Ray is a tool under ProjectV developed by VictoriaRaymond and its community group. V2Ray can run independently or provide a simple operation process together with other tools. Basically, V2Ray, like other proxy tools, completes data transmission through a specific transit server.
