<div dir="ltr"><p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">Hi Everyone,</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I’ve been using Kea for just under a year for a home setup
on a Linux Ubuntu server. I switched from
isc dhcp since it was end of life. My
setup has a lot of MAC address reservations with some general pools for systems
that don’t have IP reservations.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I also have a few vlans set up with the reservations for
devices on each of the vlans. I’m using pfSense
as my gateway with some Unifi equipment that is vlan aware.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I’m running into an issue and I’m not sure why and would
love some advice on how to look into this.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I have the interfaces on the system setup that is running
Kea, to advertise on the untagged network [mostly some servers], vlan 11 [user
systems], and vlan12 [IoT devices].</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I don’t have the firewall in pfSense to block traffic between
these networks yet, so they can all freely talk to each other.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">Even though I have my Kea configured to advertise on all of
the interfaces [untagged, 11, 12], I can’t seem to get anything to work unless
I have the DHCP Relay service setup on the pfSense device to redirect all DHCP
traffic to the Kea system’s untagged IP address [192.168.10.3].</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I can verify through nmap that udp port 67 is running on all
three interfaces.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">If I turn off the DHCP Relay service, I was expecting the
interfaces to pick up on the DHCP requests from devices on all of these
networks.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">This doesn’t happen and devices don’t get addresses. I’ve even watched the logs I’ve split out and
nothing is written for the duration that the relay service is turned off. As soon as I turn it back on, I start seeing traffic
again.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I’m running Kea 2.6.0.</p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"> </p>
<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">I’d love to turn the DHCP Relay off to then try to troubleshoot
another issue I’m having with bridging interfaces to VMs and then having the VM
interface assigned to a vlan other than the bridged interface. It seems to work for something else I’m doing,
but just trying to rule some things out.
Probably another post if I can figure out why the DHCP Relay seems to
need to be on.</p>

<p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">Any ideas why I need the DHCP Relay service on another device even though all
of the interfaces on each respective vlan are configured to listen for dhcp
requests?</p><p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif"><br></p><p class="MsoNormal" style="margin:0in;font-size:12pt;font-family:Aptos,sans-serif">-Ubence</p></div>
