confronted to the same pb for SpaceWire interopearbility testing, they devised a scheme enabling to circumvent firewall filtering pb. This scheme , called “spacewire internet tunnel server”, is described in section 4 of the attached paper. This server is setup
on an external machine and act as a relaying server for the bidirectional traffic. Is this of any value for the analysis you are performing to solve the interoperability pb over the internet.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Dear Gilles,</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">please find below a paper about the SpaceWire Internet Tunnel which we developed some years ago to allow remote integration.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">The paper describes as well the firewall problem and the way it was solved by setting up a dedicated server to allow connection from several clients.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">A similar approach might be also applicable for inter-operation testing.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Regards,</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Martin</span> <br>
