<p class="v1v1MsoNormal"><span style="mso-fareast-language: EN-US;">Hi!</span></p>
<p class="v1v1MsoNormal"><span style="mso-fareast-language: EN-US;"> </span></p>
<p class="v1v1MsoNormal"><span style="mso-fareast-language: EN-US;">It depends on use case. For me, such probe would be fine for one-off measurements but for continuous measurements I would filter out such probe to avoid noise in data. However, when I looked on freifunk.net map I noticed that this network span across Germany, Switzerland, and Austria so even for one-off measurements usage of such probe is questionable because I never know where remote end of the tunnel is. If I understand correctly it can jump from country to country every day. In other words, such probe would be tricky to handle and user will have to be aware how such probe behave to properly handle data generated by it. Probably new system tag would be needed to mark such exotic probe.</span></p>

<p class="v1v1MsoNormal">is set up as a tunnel to various ISPs (for-profit companies and</p>
