<p class="MsoNormal">Hi all,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><span lang="EN-US">I have a (hopefully) simple question. I have a KEA DHCPv6 server v2.0.3 running on a Ubuntu 20.04 machine. I am trying to get it to respond to solicitations coming via an ISC DHCPv6 relay, but I see no activity from my
DHCPv6 server when the relayed solicitations arrive. Is there any specific configuration in KEA needed for this to work, or can I troubleshoot it somehow? I can see the solicitations coming in on the correct network device using tcpdump. Solicitations that
are not relayed are handled correctly by the DHCPv6 server.<u></u><u></u></span></p>
