dhcpd sending on the same IP it receives on

My DHCP server has multiple ips on its primary NIC. For example:
eth0 = 184.108.40.206
eth0:0 = 220.127.116.11
I have my access equipment set to send DHCP relay to 18.104.22.168, but
when the DHCP server responds it sends the response packet out via
the 22.214.171.124 address since that is the primary address on that NIC.
This causes my access equipment to drop the packet because the IP it
sent to, and got the response from do not match.
Is there way to tell the dhcpd daemon to send the packets outbound
using the same IP (interface) that it received the packet on?
The simple answer is to reverse the IPs so that 126.96.36.199 is the
primary, but that's not really feasible since I have other services
that require that 188.8.131.52 be the primary IP.
