For an example of filtering rules you can search them in https://wiki.mikrotik.com/wiki/Main_Page
On MikroTik devices, all filtering rules are managed through the firewall, which is an integral part of RouterOS, the operating system used by these devices.
To find and manage filtering rules on a MikroTik device, you can follow these steps using mainly the WinBox graphical interface, which is one of the most common and easy-to-use management tools for MikroTik.
You can also access these settings through the web interface (WebFig) or via the SSH command line.
Access Filtering Rules in WinBox:
- Connect to the MikroTik Router:
- Open WinBox and connect to the MikroTik device by entering the IP address, username and password.
- Go to Firewall:
- Once inside WinBox, navigate to “IP” in the main menu and then select “Firewall”.
- View Filtering Rules:
- Within the Firewall menu, you will find several tabs. Filtering rules are found under the tab “Filter Rules”.
- This tab displays all active filtering rules that control inbound, outbound, and transit traffic through the router.
Access Filtering Rules in WebFig:
- Web Access:
- Access MikroTik using a web browser by entering the device's IP address.
- Navigate to Firewall:
- In the web interface, find the menu “IP”, then select “Firewall”.
- Review Filtering Rules:
- Similar to WinBox, you will be able to see the filtering rules under the tab “Filter Rules”.
Access SSH/CLI Filtering Rules:
- SSH connection:
- Connect to the MikroTik router using an SSH client.
- CLI Commands:
- Once connected, you can list all the filter rules by running:bashCopy code
/ip firewall filter print
- This command will display all filtering rules configured on the device.
- Once connected, you can list all the filter rules by running:bashCopy code
Tips for Managing Filter Rules:
- Regular Review: It is important to regularly review and update filtering rules to ensure that they comply with current security policies and are effective against new or emerging threats.
- Configuration Backup: It is always advisable to backup your firewall settings before making significant changes.
- Documentation: Keep all rules documented to facilitate management and diagnosis in case of problems or security reviews.
Managing filtering rules in MikroTik effectively will help you secure your network and control traffic precisely, contributing to the security and optimal performance of your network infrastructure.
