Using the default configuration on a MikroTik router may be advisable in several scenarios, especially when looking for simplicity and quick basic configuration.

We mention cases where this could be useful:

Fast Implementation

When you need to get a router up and running quickly and do not require specific or advanced configurations. MikroTik's default configuration provides a basic set of firewall rules, DHCP enabled on the LAN interface, and NAT on the WAN interface, which is sufficient for many small or home network environments.

Test Environments

If you are setting up a lab or test environment to experiment with RouterOS or for training. The default configuration allows you to start with a known and stable base, allowing you to modify or expand the configuration as needed for your tests.

Settings Reset

After a system reset or if there have been problems with previous configurations that have caused abnormal behavior or network errors. Restoring to default settings can serve as a starting point to reconfigure the device in a more controlled and safe way.

Non-Expert Users

For users who do not have advanced knowledge of networks or MikroTik RouterOS. The default configuration provides a safe way to operate the device without the need for complex settings that could compromise network security if not implemented correctly.

Technical Support Situations

When providing technical support and need to ensure that any custom settings or configuration errors are not the cause of a network problem. Starting with the default configuration can be a good starting point for systematic troubleshooting.

It is important to remember that while the default configuration may be adequate for basic scenarios, it is essential to review and adjust the security and network configurations to ensure that they meet the specific needs and appropriate security standards for your particular network environment.
