Using a VPN itself does not allow a customer to bypass the speed limitations imposed on a MikroTik router, or any other router. Speed ​​restrictions or bandwidth limits are generally applied at the network level and affect all traffic that passes through the router, regardless of whether that traffic is encrypted by a VPN or not.

How Speed ​​Limits Work on a Router

1. Queue Configuration: MikroTik routers, like many other routers, use a queuing system to manage network traffic. These queues can be configured to limit the amount of bandwidth available to certain users, IP addresses, or specific connections.
2. Rules Application: Rate limiting rules are applied based on the source and destination IP address, ports, protocols and other parameters of the packets passing through the router. These rules are effective regardless of the content of the traffic, since they operate at a lower level than VPN encryption.

What Impact Does VPN Have?

1. Encryption and Traffic Hiding: A VPN encrypts the content of data traffic, meaning that the details of the content cannot be inspected by the router. This may prevent throttling based on traffic type (for example, streaming or large downloads) but does not affect speed limitations applied at the connection or IP level.
2. Change of Source IP: While a VPN can change the IP address perceived by services external to the router, the router can still identify traffic coming from the device's local IP address. Therefore, any limitations applied to that local IP will still be effective.

Considerations

• Use Policies: Although a VPN does not allow you to bypass speed limitations, it is important to remember that excessive use of VPN may be against the policies of some ISPs or managed networks, especially if it is used to bypass controls such as access blocks or similar .
• Latency and Overload: Using a VPN can introduce additional latency and slight overhead, which could make the connection appear slower, especially if the VPN server is geographically distant or overloaded.

In short, while a VPN can help protect user privacy and avoid certain types of traffic throttling based on deep packet inspection, it cannot overcome speed limitations imposed at the router level, as these apply to everyone. data passing through the network interface, regardless of whether it is encrypted or not.
