In the world of networking, there’s often a need to bridge two remote LANs so they behave like a single local network—even when separated by different routers. For MikroTik users, the concept of EoIP (Ethernet over IP) is familiar: it’s a proprietary tunneling protocol that allows creation of a virtual Ethernet interface (Layer 2) over an IP network.

Good news for Keenetic users: since firmware NDMS v2.10, Keenetic routers also support EoIP! This opens up exciting possibilities for advanced network designs.

In a world where cyberattacks are becoming increasingly sophisticated, protecting remote access to servers and network equipment is of paramount importance. Simply opening ports for SSH, RDP, or web interfaces makes them targets for constant scanning and brute-force attacks.

Today, we’ll explore a powerful yet lesser-known technique that significantly improves the security of your MikroTik (and not only): Port Knocking. It’s not just about “closing ports,” but a smart system that makes your services invisible to most scanners and bots.
