How to define dhcp server to only serve specific nic

[Tadaen_Sylvermane]

I'm looking at a guide to add a squid transparent proxy to my network. http://www.purplealienplanet.com/node/25 is the guide I am looking into. What I need though since everything is on a common switch, how can I instruct the dhcp server (using isc-dhcp-server) to only serve dhcp addresses on the virtual network interface. In my case enp2s0:0. Not on the default enp2s0. I don't want to knock out the network at my home as it is serving a number of smaller apartments on my property (grandparents, parents, and my place on a shared piece of land). I need to get it right the first time.

Hi Tadaen_Sylvermane.

You should be able to list the interfaces you want to serve in this file:

/etc/default/isc-dhcp-server

Look for the line that looks like this:

INTERFACES=""

and change it appropriately. For example:

INTERFACES="enp2s0:0"

Then restart the dhcp ervice:

sudo systemctl restart isc-dhcp-server.service

Hope it helps. Let us know how it goes.
Regards
