world for offering such professional open source software. </span></p>
<p><span style="font-family:arial,helvetica,sans-serif">Now my issue I have 2 pc's connected with a cross cable,
with connectivity between them using ipv6 both have
installed kea 1.2.0 with log4cplus-2.0.0 and openssl writing
the leases to a mem file. One of these pc's is designed to
be the dhcp server (alias mozo 2001:db8:beef:55::2 or
10.0.0.2) and the other only uses the perfdhcp tool to
stress test the dhcp server (alias geek 2001:db8:beef:55::3
or 10.0.0.3). My goal is to establish a statefull dhcpv6
environment.</span></p>
<p><span style="font-family:arial,helvetica,sans-serif">I successfully completed the stress test using perfdhcp
with ipv4, but for some reason when i start the ipv6 stress
test i get the following result:</span></p>

The leases file is empty and the same issue occurs with
isc-dhcp-server (dhcpd6). Just in case i disabled ip6tables
in both machines and SELinux. Both pc's are running centos
6.9 and the server acts as a RA. </span></p>

appreciated. I can provide the config files via email if you
wish.</span></p>
