configured the following lines on /etc/dhcp/dhcpd.conf: </div><div><br /></div><div>default lease-time 600;</div><div>max-lease-time 7200;</div><div><br /></div><div>subnet 10.0.0.0 netmask 255.255.0.0 {</div><div> range 10.0.0.10 10.0.200.200;</div><div> option subnet-mask 255.255.0.0;</div><div> option routers 10.0.0.1;</div><div> option domain-name-servers 8.8.8.8, 8.8.4.4;</div><div>}</div><div><br /></div><div>subnet 192.168.120.0 netmask 255.255.255.0 {</div><div>}</div><div><br /></div><div>When I start the server, I only see it trying to answer requests using network 192.168.120.0, then saying "no free leases", and not serving any <a href="http://10.0.0.0/16">10.0.0.0/16</a> address.</div><div><br /></div><div>Now I'm living with TFTPD64, but I plan to move that to a better solution.</div><div>Does anybody know about this configuration?
