Hello All,<br><br>I am trying to set up a cobbler server running as a guest on an isolated network. I&#39;m having trouble figuring out how I can forward the DHCP and DNS traffic to this guest instead of DNSMASQ on the host.  So far I have only tried to get dhcp working by enabling the 
&#39;allow-dhcp-server&#39; on a guest named test and setting the $DHCPSERVER variable through a filterref parameter element. I figure If I can get this 
working I can use this filter as a basis for DNS. <br><br>In my guest the filter is applied to the only network interface setting DHCPSERVER to the IP of my cobbler VM.<br><br>    &lt;interface type=&#39;network&#39;&gt;<br>
      &lt;mac address=&#39;52:54:00:6b:56:ab&#39;/&gt;<br>      &lt;source network=&#39;internal&#39;/&gt;<br>      &lt;target dev=&#39;vnet2&#39;/&gt;<br>      &lt;model type=&#39;virtio&#39;/&gt;<br>      &lt;filterref filter=&#39;allow-dhcp-server&#39;&gt;<br>
        &lt;parameter name=&#39;DHCPSERVER&#39; value=&#39;192.168.100.2&#39;/&gt;<br>      &lt;/filterref&gt;<br>      &lt;address type=&#39;pci&#39; domain=&#39;0x0000&#39; bus=&#39;0x00&#39; slot=&#39;0x03&#39; function=&#39;0x0&#39;/&gt;<br>
    &lt;/interface&gt;<br><br>And the internal network is defined as:<br><br>&lt;network&gt;<br>  &lt;name&gt;internal&lt;/name&gt;<br>  &lt;uuid&gt;c1aef8ea-9d30-7514-5eb4-5ffbc235cffb&lt;/uuid&gt;<br>  &lt;bridge name=&#39;virbr1&#39; stp=&#39;on&#39; delay=&#39;0&#39; /&gt;<br>
  &lt;ip address=&#39;192.168.100.1&#39; netmask=&#39;255.255.255.0&#39;&gt;<br>  &lt;/ip&gt;<br>&lt;/network&gt;<br><br>My understanding of the filter is that when it is applied to a hosts interface it should allow DHCP requests to go to a server other than the host system. Is this correct? Are guests allowed to serve DHCP to other guests?<br>
<br>Does anyone have any suggestions or experience with this?<br><br>Thanks in advance,<br><br>Adam Reid<br><br>
