configuring isc-dhcp-server

**sniper8752** · November 18th, 2020

I am trying to configure this, and I set my interfaces variable to my internal interface on my server. After I do a restart of the service, I see that it is listening as follows:

Code:

udp        0      0 0.0.0.0:67              0.0.0.0:*                           2850/dhcpd

This means all interfaces, right? Is there any way to prevent this from happening?

Try specifying the interface on the command line. I haven't used dhcpd for a while myself, but I recall it was as simple as:

Code:

/usr/sbin/dhcpd eth1

That did not work.
I started it, did a status, and it says no subnet declaration for the external interface, so it's ignoring requests there, which is what I want, but I am surprised there isn't a way to just tell it to only listen on a certain interface.
