[Kea-users] kea-dhcp4 and interface binding

[John Ratliff]

I'm trying to run kvm on the same machine I'm using kea-dhcp4 as my DHCP 
server. When I have kea running, I can't start the NAT default network 
for kvm. It says that something is already listening on the ports that 
dnsmasq wants to use for DHCP on the virtual bridge interface. I asked 
on the kvm list and they told me that dnsmasq is configured to only 
listen on that virtual bridge interface, and I would need to configure 
kea to only listen on my lan interface.

I setup kea to use my device, but it doesn't seem to bind it to that 
interface.

Is there a way to keep kea from binding to all interfaces?

My kea-dhcp4 config file is here: https://pastebin.com/SrWBN4wQ

I'm using kea v1.3.0 on Arch Linux.

I noticed this from ss -tupln. IT looks like Network Manager is only 
binding on the ethwan interface. I saw on dnsmasq when I started it from 
virsh when kea was stopped that it had a similar % marker suggesting it 
was bound only to ethlan.

udp    UNCONN     0      0      192.168.5.1:67                 0.0.0.0:* 
                   users:(("kea-dhcp4",pid=4411,fd=10))
udp    UNCONN     0      0      66.244.72.1%ethwan:68 
0.0.0.0:*                   users:(("NetworkManager",pid=435,fd=15))

Thanks.
