However, if you use UDP, it is recommended that you set “mssfix 1330” in the client configuration. If you don’t want to be de-anonymized by means of this method, you can manually set up “mssfix 0” on the server and “mssfix 0” on the client. MTU allows to obtain these parameters and determine the very fact of OpenVPN usage. Setting up OpenVPN requires a non-standard MTU parameter depending on the connection protocol, traffic encryption algorithm, consistency check algorithm, and compression. In the majority of cases, the MTU value for VPN is 1450. The 1500 MTU value means that the connection can allow only up to 1500 bytes of traffic. A standard MTU value for a cable connection is 1500. 1490, 1480, 1470 until you get a successful reply. If the reply you get is ping: sendto: Message too long, then you have to try a lower MTU value.Keep decreasing the value by 10, i.e. Optimize your Max MTU Setting for the Internet How to determine the Max MTU size for an optimal internet connection Information on the Internet is transferred in packets. To set the best MTU value and optimize Internet speed, please perform the following steps: 1 Open Terminal. And set the traffic to not fragment and manually set the packet size. The MTU parameter is assigned by the network interface. For your MTU, because traffic is fragmenting over a VPN connection. Maximum Transmission Unit, or MTU, is a maximum amount of transmitted information sent by one data package. How can VPN use be tracked at the first place? MTU parameter Besides, our client offers other benefits such as simultaneous access from multiple devices, reliable channels, and no speed cap. We recommend to use VPN because it allows you to change your MTU with just one click.

Can you avoid this somehow? In fact, with VPN yes, you can!

Sometimes the use of VPN can be detected by analyzing the TCP connection based on the MTU size. Some use them to access blocked sites, others want to bypass geolocation rules. VPN services are utilized by many Internet users today.
