Ubuntu 18.04 DHCP server 관련 (client가 remote에 있는 환경)

안녕하세요.
Ubuntu 18.04 에서 DHCP server 를 구동하려 합니다.
그런데, direct network이 아니라, remote network 환경입니다.
따라서, 서버와 client 사이에 relay agent가 있는 구성입니다.

DHCP server ----------- DHCP Relay Agent------------- DHCP client
(10.1.1.1/24) (10.1.1.2/24) (10.100.100.1/24) (10.100.100.0/24)
(10.200.200.1/24) (10.200.200.0/24)

위와 같은 구성에서, isc-dhcp-server 를 구동시키니 계속 에러가 발생합니다.
subnet이 10.1.1.1/24와 일치하지 않아서 발생하는 것으로 보입니다.
--> subnet을 10.1.1.0/24 로 일치시키면, 정상 동작합니다.
혹시, 이런 구성에서 DHCP server를 구동시킬수 있는 옵션이나 설정이 있을까요?
미리 감사드립니다.^^

//에러 메세지
No subnet declaration for ens33 (10.1.1.1).
** Ignoring requests on ens33. If this is not what you want, please write a subnet declaration
in your dhcpd.conf file for the network segment to which interface ens33 is attached. **

Not configured to listen on any interfaces!

If you think you have received this message due to a bug rather No subnet declaration for ens33 (10.1.1.1).
than a configuration issue please read the section on submitting bugs on either our web page at www.isc.org or in the README file before submitting a bug. These pages explain the proper process and the information we find helpful for debugging..
