DHCPd using wrong interface

[Dan Egli]

I am completely stumped on how to solve this one. I have a machine with 
two NICs. It's my gateway machine between my home private LAN and the 
internet. The gateway machine has enp0s3 with an address of 10.0.2.15 as 
it's world facing address (yes, my ISP wants to run everything through 
NAT. Don't ask me why). The LAN address range is `192.168.10.0/24 on 
enp0s8.  I configured dhcpd to completely ignore anything coming from 
10.0.0.0/8, and I even have enp0s8 listed on the command line (and NOT 
enp0s3). Yet when dhcpd tries to send update requests to bind, it keeps 
using the 10.0.2.15 address, which bind properly refuses to listen to. 
How do I make dhcpd send messages from enp0s8's 192.168.10.2 address vs 
the 10.0.2.15 address?
