VPN ports are virtual communication endpoints crucial for establishing secure connections between a client’s device and a VPN server. Let’s dive into the details:

1. Understanding VPN Ports:
   • VPN ports serve as digital gateways for internet connections. Each port has a specific number associated with a particular process, allowing networks to route traffic effectively.
   • When you connect to a VPN, your encrypted data travels through a tunnel to a VPN server. The VPN port acts as the starting point for this journey and the endpoint when data returns to your device.
2. Types of VPN Ports:
   • VPN protocols use different port numbers. Here are some common ones:
     • WireGuard: Uses UDP port 51820.
     • OpenVPN: Uses UDP port 1194 and TCP port 443.
     • IKEv2: Uses UDP ports 500 and 4500.
     • PPTP, SSTP, L2TP, and IPSec: Each has its own set of port numbers¹.
3. Port Forwarding:
   • Port forwarding allows specific traffic to bypass firewalls and security measures. It tells your router that certain traffic is safe and shouldn’t be blocked.
   • While it’s useful for remote access and secure servers, port forwarding has security flaws and is not offered by premium VPNs like Surfshark.

In summary, understanding VPN ports helps you optimize your connection and ensure secure data transfer. Remember to choose the right VPN protocol based on your needs and prioritize security over speed.
