That's what I figured but wanted to be sure.<br>

That can be typical in some networks as a lot of firewalls drop ICMP
packets by default.<br>

AFAIK everything looks fine. Can't give you an definitive answer as
to why when Kea sends a packet the OS thinks the host has no route:<br>
<br>
- Could be a firewall or security context issue. Check IPTables,
AppArmor, SELinux, etc.<br>
- As a test you could try changing to raw sockets (remove <font
face="Droid Sans Mono">"dhcp-socket-type": "udp"</font>). If that
does work I'm not sure why it would as it's a relayed request.<br>
- Force Kea to use the kernel routing table by adding <font
face="Droid Sans Mono"><span class="s2">"outbound-interface"</span><span
class="p">:</span> </font><span class="s2"><font face="Droid
Sans Mono">"use-routing" </font>to the configuration (after
re-adding <font face="Droid Sans Mono">"dhcp-socket-type": "udp"</font>
back to the config).<br>
