MikroTik RouterOS powers many enterprise and ISP networks. A VPN on MikroTik gives remote access and site‑to‑site tunnels. Without proper security your network may face data theft, DDoS, or persistent malware. This article shows how to design and secure VPN on MikroTik. You will learn about vulnerabilities, protocol choice, configuration, firewall, monitoring, and hardening. It…
A transparent firewall filters network traffic without acting as a gateway. It works in Layer 2, meaning it processes packets without changing their destination or source IP addresses. This setup is common in enterprise networks where stealthy packet filtering is required between internal and external segments. MikroTik RouterOS offers a powerful and cost-effective way to…
Simple Guide to MikroTik Routers: Login, Configuration, WiFi, Default Password, Prices & More You’ve probably searched for things like “MikroTik router login,” “MikroTik configuration,” or “MikroTik default password.” In this simple but also complete guide, we’ll answer all the most common questions users ask about MikroTik routers—including setup, WiFi configuration, default settings, and popular models…
DDoS attacks attempt to disrupt normal traffic by overwhelming the target with a flood of Internet traffic. MikroTik routers offer powerful protection features that can stop most DDoS attacks when configured correctly. This guide provides practical protection strategies for network engineers managing MikroTik infrastructure. You will learn to implement both basic and advanced protection measures…
Ethernet over IP (EoIP) is a tunneling protocol that enables the encapsulation of Ethernet frames within IP packets. This allows for the extension of Layer 2 networks across Layer 3 infrastructures, facilitating seamless connectivity between remote sites. This guide provides a detailed overview of EoIP, its operation, benefits, configuration, and considerations for network engineers and…
In this article, we’ll explain the basics about IP addresses, subnet masks and subnets. If you use Windows OS and you enter ipconfig in Command Prompt, chances are that somewhere in the output you’ll see something like: IPv4 Address. . . . . . . . . . . : 192.168.0.11 Subnet Mask . ….
Point-to-Point Protocol over Ethernet (PPPoE) continues to serve as a fundamental protocol in Internet Service Provider (ISP) networks worldwide. Despite the emergence of newer technologies, PPPoE offers distinct advantages for user management, authentication, and accounting that maintain its position as a preferred choice for many ISPs. MikroTik RouterOS provides a powerful and cost-effective platform for…
SNMP stands for Simple Network Management Protocol. It lets you gather data from network devices and is used by network engineers and systems administrators. This article explains SNMP configuration on MikroTik devices. You will learn how to set up basic SNMP settings, secure the configuration using SNMP v3, test your configuration, and follow best practices…
In today’s digital era, data is the new currency. For network engineers and systems administrators, selecting the right file storage solution is crucial to maintaining performance, security, and scalability. This article provides a deep dive into the world of cloud file server vs. on-premise file servers. We’ll explore the technical nuances, cost implications, and practical…
Emulating networks in a virtual environment has become an essential tool for network engineers and system administrators. Whether you’re testing new configurations, simulating network failures, or learning advanced routing techniques, network emulation offers a risk-free and cost-effective solution. This article provides a step-by-step guide on MikroTik network emulation with GNS3, highlighting practical configuration examples and…
