Applies to: RouterOS v6 and v7 (IPv4). Behaviour differences between releases are called out where they matter. Contents Why relay exists: the broadcast domain problem How RouterOS relay works: giaddr is the whole mechanism Architecture: where the relay sits in a VLAN design Configuring relay for multiple VLANs Server-side configuration: the relay= property Option 82:…
Applies to: RouterOS v6 and v7. Policy availability varies by release; verify against your version’s CLI reference before rolling out. Contents How RouterOS authorisation actually works The policy reference Why the built-in groups are a poor RBAC baseline Policy negation: add versus set Designing a least-privilege role model Hardening the accounts themselves Centralised RBAC with…
A practical MikroTik RouterOS maintenance guide covering safe upgrades, backups, release channels, verification, exact-version downgrades, and RouterOS v6/v7 migration risks.
MikroTik DNS Cache and Web Proxy: Optimizing Internet Access MikroTik RouterOS includes two built-in caching mechanisms that are often confused but serve very different purposes: the DNS cache and the web proxy cache. Used correctly, they reduce latency, lower upstream bandwidth consumption, and improve the browsing experience for LAN clients. Used incorrectly, they can waste…
The best free Linux tools for checking hard drive and SSD health are smartmontools (smartctl and smartd), nvme-cli, GSmartControl, Scrutiny, and badblocks. Together they read S.M.A.R.T. data and NVMe health logs, run drive self-tests, track health over time, and scan for unreadable blocks. This guide explains what each tool does, gives the exact commands, and…
