[Kea-users] Multiple Subnets - 1 NIC

[Maxime Lareo]

Hi,

I currently testing KEA with 2 servers for HA with a Mariadb Galera 
Cluster Backend and it works pretty well.

It running like a charm with one subnet, but when it come managing 
multiple subnet, with only 1 NIC, it seems impossible to make it work. 
KEA just doesn't want to give an IP address that doesn't belong to its 
own subnet.

I don't succeed to use ip relay or client classification properly to 
make it work.

Do I missing something ?

I just want to have VoIP devices on another subnet than the original 
subnet. All the devices (VoIP or not) are on the same VLAN and switch.

To explain my actual configuration :

I have a client classes testing the option 60 and it work, I can see in 
the log file, the expression evaluated to 1, but KEA doesn't choose the 
subnet with the client-class but the one who match its subnet (the one 
my server ip address belong to), which is after the VoIP subnet in the 
conf file.

Someone know a way to make it works ?

Thank you !
