Question 1

What is Simneta NetLab and how does it work?

Accepted Answer

Simneta NetLab is a free, interactive in-browser network lab (NetLab). It enables students, network engineers, and academy instructors to design topologies, configure core routers and switches, and inspect packet flow in real time without downloading software or setting up heavy virtual machines like GNS3, EVE-NG, or NDG pods.

Question 2

How does Simneta NetLab differ from NDG NETLAB+ and Cisco Packet Tracer?

Accepted Answer

Unlike traditional NDG NETLAB+ which requires physical school hardware pods and server scheduling, Simneta NetLab runs 100% inside your modern web browser with zero installation. Compared to desktop Cisco Packet Tracer, Simneta NetLab runs effortlessly on Chromebooks, macOS, Windows, and Linux without local licenses.

Question 3

Do I need to install any software to use Simneta NetLab?

Accepted Answer

No installation is required. Simneta NetLab runs directly inside modern web browsers (Chrome, Edge, Firefox, Safari). You can open a lab on any computer or laptop and begin practicing immediately.

Question 4

Is Simneta NetLab free to use for personal learning?

Accepted Answer

Yes. All interactive learning modules, NetLab practice sandboxes, and foundational tutorial labs are completely free to access. You can explore, simulate, and complete hands-on challenges without entering a credit card.

Question 5

How does live packet flow visualization work?

Accepted Answer

When devices communicate—such as when a workstation issues an ARP request, a DHCP DORA exchange occurs, or an ICMP ping is sent—the simulator animates packet indicators along the connected cables in real time with protocol labels and transmission status.

Question 6

What cable types and link speeds are supported?

Accepted Answer

Simneta supports standard copper Cat6 Ethernet connections (1 Gbps) with Auto-MDIX negotiation, Fiber SFP+ optical links (10 Gbps), and WAN cloud uplinks. You can customize cable colors, styles, and inspect port states in the Cable Inspector drawer.

Question 7

How does real-time task auto-detection work in chapter lessons?

Accepted Answer

In module chapters, the built-in simulator engine observes canvas events (such as connecting an Ethernet cable, opening a terminal, or successfully receiving ping replies). When you complete an action, the corresponding checklist task ticks off automatically.

Question 8

Which router and gateway features are simulated?

Accepted Answer

Simneta simulates core routing and gateway capabilities including IP address configuration, bridge interfaces, DHCP Server & IP Pools, default routing, firewall NAT masquerade, DNS caching, and IEEE 802.1Q VLAN filtering.

Question 9

Can I use both visual management consoles and the CLI Terminal?

Accepted Answer

Yes. Double-clicking a router node opens an inspector featuring both an authentic web-based graphical management interface and a command-line terminal supporting standard network commands.

Question 10

Can I export my visual topology as configuration scripts?

Accepted Answer

Yes. Simneta can generate clean network configuration scripts representing your visual network design, which you can export and run directly on physical hardware routers.

Question 11

What is the difference between Tutorials and Modules?

Accepted Answer

Tutorials are standalone, topic-focused laboratory guides (like setting up a gateway or troubleshooting packet loss) paired with interactive lab topologies. Modules are structured, multi-chapter learning tracks (like Computer Networking Basics or Office DHCP Setup) designed for sequential learning with step-by-step sandboxes.

Question 12

Can Simneta help with MTCNA, MTCRE, or CCNA certification prep?

Accepted Answer

Yes. The learning modules cover foundational concepts tested in official network certifications, including subnetting, routing tables, broadcast domains, VLAN tagging, and gateway masquerading.

Question 13

How do I save or fork public tutorials to my private dashboard?

Accepted Answer

When viewing any tutorial, click the Fork Lab button in the sidebar. If signed in, a duplicate copy of the entire lab and device configuration is immediately created in your personal dashboard workspace.

Question 14

Where are my saved labs stored?

Accepted Answer

Labs are saved securely to your account profile and cached in local browser storage, allowing you to resume your simulation setups from anywhere.
