MikroTik RouterOS DHCP Configuration Simplified Guide

Are you familiar with rogue DHCP? If not, you are in the right place because in this post, we will be discussing how to enable rogue DHCP detection on your Mikrotik RouterOS. But first, let’s define what rogue DHCP is.

Rogue DHCP refers to a malicious attacker who sets up a DHCP (Dynamic Host Configuration Protocol) server on a network without authorization. When there are multiple DHCP servers running on a network, it can cause conflicts and communication issues among devices. Rogue DHCP can also lead to cyber-attacks such as malware deployment, data interception, and website hijacking.

Why is Rogue DHCP Detection Important?

Enabling rogue DHCP detection on Mikrotik RouterOS is crucial for network administrators to prevent unauthorized DHCP servers from accessing their network. DHCP servers are responsible for assigning IP addresses and network information to devices on a network. If a rogue DHCP server is connected, it can assign invalid IP addresses and other network information to devices on the network, which can cause problems and security issues.

How to Enable Rogue DHCP Detection on Mikrotik RouterOS

To enable rogue DHCP detection on your Mikrotik RouterOS, follow these simple steps:

Log in to your Mikrotik RouterOS and go to the DHCP server menu.
Select the "detect-rogue" option.
Choose the interface where you want to enable rogue DHCP detection.
Save and apply the changes.

After you have enabled the rogue DHCP detection, the Mikrotik RouterOS will periodically scan the network for rogue DHCP servers. When a rogue DHCP server is detected, the Mikrotik RouterOS will send a notification alert to the network administrator, and the rogue DHCP server will be blocked from accessing the network.

Conclusion

Enabling rogue DHCP detection on your Mikrotik RouterOS is vital to prevent unauthorized DHCP servers from accessing your network. By following the simple steps outlined in this post, you can enable the detect-rogue option and select the interface on which to enable it. This will enable your Mikrotik RouterOS to scan for rogue DHCP servers on the network and notify you if one is found, protecting your network from various cyber-attacks.
