What should be set to prevent access from a specific IP address to your router's web interface?

To effectively prevent access from a specific IP address to your router's web interface, it is essential to utilize both the firewall filter and the WWW service configurations. The firewall filter acts as a gatekeeper, where you can specify rules that control traffic entering your router, including traffic targeting the web interface. By creating a specific rule to drop or reject traffic from the undesired IP address in the filter chain's input chain, you can directly restrict access before it even reaches the web service.

Additionally, the WWW service settings allow you to define which IP addresses can access the web interface of the router. You can specify a list of allowed IP addresses, thereby preventing any connections that do not meet this criteria. When these two methods are combined, you achieve a comprehensive security layer: the firewall effectively blocks unwanted traffic at a fundamental level while the WWW service settings provide an additional point of control.

Utilizing both these methods ensures a more robust approach to preventing unauthorized access, which highlights the importance of administering both firewall rules and service permissions to reinforce security on your MikroTik router.
