Introduction

A firewall is a crucial security measure that protects your computer from unauthorized access by blocking incoming network traffic. Configuring your firewall to allow specific ports can be necessary for various applications and services to function correctly. This article provides a detailed guide on how to add a port to the firewall in Windows 10 2025.

Understanding Ports

A port is a logical endpoint in a network communication system. It identifies a specific service or application running on a computer. Each port is assigned a unique number, ranging from 0 to 65535. When data is transmitted over a network, it is assigned to a specific port on the destination computer.

Why Add a Port to the Firewall?

Adding a port to the firewall allows incoming network traffic on that port to reach the intended application or service. This is necessary when you want to:

• Enable remote access to a specific service (e.g., web server, FTP server)
• Allow communication with devices on a local network (e.g., printers, NAS drives)
• Run applications that require access to specific ports (e.g., games, video conferencing software)
