Tools that explain the why, not only the command

Each tool runs in the browser, shows the assumptions behind the output, and gives you a verification path before you change a live ISP router.

How to choose: use the IPv4 tool to plan addresses, WireGuard for secure remote access, Port Forwarding only for a deliberately exposed service, QoS for shaping after you understand packet direction, and Wireless Link Budget before you install a radio link.

Core tools

Why the explanations are part of the tool

A configuration generator without assumptions can create a false sense of safety. Every page therefore explains what the command changes, what it cannot test from a browser, and what evidence to collect after deployment. For example, the Port Forwarding page distinguishes a NAT translation from a forward-chain permission, while the QoS page distinguishes a Simple Queue from a Queue Tree that depends on packet marks.

For production changes, export the current configuration, apply one narrow change, observe counters and logs, and keep a rollback path. The deployment checklist turns that sequence into a repeatable record.

Privacy and safety

The new tools do not call an API or upload the values in their forms. Downloaded output is generated locally. You remain responsible for replacing placeholders, checking the RouterOS version, reviewing the topology, and protecting private keys and management services.
