  Understanding Mikrotik Port Forwarding Port forwarding is a crucial concept in modern networking, especially for administrators managing routers like Mikrotik. This guide will walk you through the  necessity of port forwarding , its benefits,  Mikrotik firewall rules , and its associated cybersecurity challenges. Whether you’re a network engineer or an enthusiast, mastering port forwarding is essential for optimizing your network. In this post, we’ll also discuss how to mitigate vulnerabilities and safely manage port forwarding. I have make a description Video of this purpose in youtube if anyone interested or learn more please  click here to find it out.   What is Mikrotik Port Forwarding? P ort forwarding allows remote devices to connect to services on your internal network through a router. Typically, routers block incoming traffic from the outside world to ensure security. Port forwarding creates a controlled exception to this rule by opening specific port...

  Cybersecurity Basic Knowledge. Introduction to Cybersecurity In an era dominated by technology, cybersecurity has emerged as a critical field dedicated to protecting systems, networks, and programs from a wide range of digital attacks. These attacks can take many forms, often aiming to access, alter, or destroy sensitive information, extort money from individuals and organizations, or disrupt essential business processes. The proliferation of internet-connected devices and the increasing sophistication of cyber threats underscore the necessity for robust cybersecurity practices. As such, understanding the fundamental concepts and practices of cybersecurity is crucial for both individuals and organizations looking to safeguard their data and maintain the integrity of their operations. The Importance of Cybersecurity Cybersecurity is not merely a technical issue; it is a vital business concern that has far-reaching implications. The potential impacts of cyber threats extend beyond ...

  Mikrotik PPPoE and everything related to PPPoE  This content covers the various aspects of PPPoE (Point-to-Point Protocol over Ethernet) configuration and its significant features when implemented on MikroTik routers. In this content we have tried to describe every aspect of PPPoE elaborately from bandwidth management and network control to enhanced security and user identification, PPPoE plays a crucial role in delivering structured and efficient network services.We have attached youtube video for this configuration and for better understanding we have also attached the video of configuring the PPPoE in real field. Each section explains the key elements of PPPoE, providing insights into how it facilitates network stability, user security, and encryption mechanisms. PPPoE on MikroTik Router: Bandwidth Management Every point is elaborately described to highlight how PPPoE on MikroTik routers allows fine control over bandwidth allocation for individual users. Administrator...

  Step-by-Step Guide to Setting Up OpenVPN on MikroTik Router The best way of create server in Mikrotik router to connect Ovpn clients as below, Here we have described every step very easily and all CLI command clearly described. I have already discussed Ipsec VPN in my another Youtube video content you can also IPsec VPN configuration .   A.      Generate Certificates for secure connection of Ovpn clients. Creating certificates is crucial for establishing a secure and encrypted VPN connection. We'll generate certificates for the Certificate Authority (CA), server, and client. Create Certificate Templates :   Command : /certificate add name=ca-template common-name=myCA key-usage=key-cert-sign,crl-sign /certificate add name=server-template common-name=server /certificate add name=client-template common-name=client These commands create certificate templates for the CA, server, and client. The ca-template is used to sign o...

  OSI Model Layers: Functions and Cyber Attacks.          What is OSI? The Open Systems Interconnection (OSI) model is a conceptual framework used to understand and implement standard protocols in networking. It divides network communication into seven distinct layers, each with its specific functions, components, and security concerns. Here's a detailed look at each layer: I have also added a detail video in the middle of the topic for your better understanding.  Physical Layer Function : Handles the physical connection between devices and the transmission of raw binary data over physical media such as cables and wireless signals. Components : Cables (Ethernet, fiber optics), hubs, repeaters. Basic Works in Networking : Transmission and reception of raw data bits, signal...
