🌐 “Virtual address” between two MikroTiks: when L2 connectivity is needed and how to do it correctly
In today’s world of networking technologies, combining two remote offices into a single entity is a fairly routine task. Usually, L3 tunnels are used for this (for example, IPIP or IPsec). However, there are situations when simple routing is not enough and full L2 connectivity is required, as if remote devices were connected to the same switch.

🌐 Embedding a Website Builder Page into Your Site via NGINX
Integrating a page created in an external website builder into your domain allows you to extend functionality and maintain a consistent interface style.

SSL certificates via DNS: automating Let’s Encrypt issuance
Introduction
Let’s Encrypt is the standard for obtaining free TLS certificates. Most often certificates are issued via the HTTP-01 method, which requires a reachable web server on port 80. However, for internal services or wildcard certificates (for example, *.example.com) it is more convenient to use DNS-01, which verifies domain ownership via TXT records in DNS and does not require open ports.

TCP Connection Proxying with HAProxy: A Beginner’s Guide
Introduction
If you are a beginner system administrator or developer, you’ve probably faced the task of managing network traffic.
One of the most powerful tools for this is HAProxy, a high-performance load balancer for TCP and HTTP.
In this article, we will cover:
- what TCP proxying is,
- why to use HAProxy,
- a sample configuration for beginners,
- security and monitoring tips.
What is TCP Proxying?
TCP Proxying is the forwarding of TCP connections from a client to a server (or group of servers) through an intermediary.
Unlike an HTTP proxy that operates at the application layer, TCP proxying happens at the transport layer, making it universal for any TCP protocol: from databases to mail services.

Case: Launching and Registering an MTProto Proxy in 5 Minutes Using Docker
Problem
In some regions, access to Telegram may be unstable or completely blocked.
Using public proxies or VPNs is not always convenient: they can be slow, overloaded, or also blocked.
Task
🚀 Create your own fast and reliable proxy, register it in Telegram to track statistics, and optionally make it public.
Solution Choice: Docker + Official MTProto Image
Why Docker?
Docker allows you to run the proxy in an isolated container without installing unnecessary dependencies on the server. It’s clean, secure, and incredibly fast.
The docker-compose.yml file describes the entire configuration in one place, making the launch and management process trivial.
