It is not possible to create a rule on a MikroTik router (or any other end-user network device) that prevents your Internet Service Provider (ISP) from measuring or calculating the total packets or data you are sending and receiving over your connection.

ISPs generally have their own systems and methods for monitoring traffic passing through their networks, and this is outside the control of the hardware or configurations that users may implement at their endpoints.

However, there are some strategies and settings you can use to manage and possibly optimize how your bandwidth is used:

1. Limit Bandwidth

You can set up rules on your MikroTik to limit the amount of bandwidth available for certain services or applications. This does not prevent the ISP from counting data, but can help manage usage within available data limits or to prioritize certain traffic over others.

2. Traffic Shaping

Using traffic shaping techniques, you can influence how and when traffic is sent across your network. This may include prioritizing certain types of traffic, such as VoIP or gaming, over bulk file downloads, which can improve the overall experience without necessarily reducing the total data used.

3. VPN

Using a VPN can encrypt your data traffic, making it more difficult for the ISP to determine the type of traffic you are generating. However, this does not reduce the amount of data being counted, as the volume of data transferred is still visible to the ISP.

4. Negotiate with the ISP

In some cases, it may be possible to negotiate specific terms of service with your ISP, especially if your data needs are high or you have specific business requirements.

5. Traffic Monitoring

Setting up MikroTik to monitor network traffic can help you better understand how your data is being used, which could allow you to make proactive adjustments to reduce unnecessary or non-priority usage.

In short, while you can't stop your ISP from counting the data you consume, you can manage and optimize how and when your data is used to get the most out of your internet connection, adapting your MikroTik's settings to align with your specific bandwidth needs.
