<p>Thanks for the report. Just briefly looked into the RFC, is the net 192.0.0.0/29 not defined as:<br>
192.0.0.1 - 192.0.0.6 ? I failed to find this IPs in your trace.</p>
<p>There is code in nathelper for this net:<br>
{"192.0.0.0",   0, 0xffffffffu <<  3}, /* rfc7335 - IPv4 Service Continuity Prefix */</p>
