Extremely hight port

[STS]

Hello. As I told Kriss in the public server weeks ago, I am making tests to use OMP in my Virtual Agency (Spanish Agency). I am using Hamachi, cause it looks that it ignores the port configuration on the PC´s. But we have a problem. When the user in the following image logs, the server assigns him a extremely high port above 3000. It assigns him a port over 49000. Why is this?

This is the beggining of the code of my Server.xml

<?xml version="1.0" encoding="utf-8"?>
<OMPServerConfiguration xmlns="http://Orbiter.Multiplayer.Server" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" Name="RacingServer" xsi:schemaLocation="http://Orbiter.Multiplayer.Server ..\Orbiter.Multiplayer.Server\Configuration.xsd" OrbiterRoot="../../" SubvisualDistance="1000000000" PromptFormat="({1:HH:MM:ss}) {0}">
    <Network IP="5.50.165.176" TCP="1515" UDP="3000" Count="500"/>
    <NTP Samples="12">
        <Server IP="time-a.nist.gov"/>
        <Server IP="time-b.nist.gov"/>
...

This is the image of the user logging and the port asigned:

It's a client side port, so it shouldn't matter if connection was established. It could be first or a random port from unassigned ports' pool. Server configuration doesn't influence client's configuration, and TCP 1515 and UDP 3000 are ports on server side.
