Alex,
<div class=""><br class="">
</div>
<div class="">The site still has to be configured so that we get ports that are acceptable.</div>
<div class="">Perhaps we don’t get external port 80 but our end can use alternate ports.</div>
<div class="">We have one site where we don’t get port 80 but we use port 8080.</div>
<div class="">There is another site where we don’t get port 22, but they have configured</div>
<div class="">external port 22222 to get translated to port 22 on the site node behind the NAT.</div>
<div class=""><br class="">
</div>
<div class="">So, it is not automatic. There is configuration needed at the site end and</div>
<div class="">at our end.</div>
<div class=""><br class="">
</div>
<div class="">It is perhaps not ideal but it is manageable.</div>

<div class="">I would like to lift the restriction about being behind a NAT. I believe that we originally put</div>

<div class="">We have already been flexible with a couple of sites that wanted or needed to be behind a NAT. </div>
<div class="">So far, I do not have any evidence that this has caused any problems. We do have an issue with</div>
<div class="">one site that happens to be behind a NAT but at this time I do not think the NAT is causing the problem.</div>

<div class="">Does anyone have any concrete reasons why an NDN node on the NDN Testbed should</div>
<div class="">NOT be allowed to be behind a NAT?</div>
