VLANs are your friend, otherwise DHCPD is not going to understand how to properly answer your request for different networks on the same interface.

| option domain-name-servers 192.168.0.1;
| }
|
| When i remove the above from dhcpd.conf dhcpd works perfectly
|
| I have my internal nic card set with two ip addresses one of which is
| 192.168.0.1. the other address is my standard internal network address.
|
| I have also set up the domain server to allow access from
| 192.168.0.0/24, and the firewall allows internal access to the same
| subnet.
|
| The error that I get is the following :
|
| Job for dhcpd.service failed because the control process exited with error code.
| See "systemctl status dhcpd.service" and "journalctl -xe" for details.

| When I evaluate journalctl -xe the following is obtained :

|
| Does anyone have any ideas? Would sure appreciate your help.
