Hello Klaus,
In addition to what Peter said, another option would be to use shared
networks and add the subnet for relays along with the subnet of
addresses that you wish to allocate to the clients to a shared
network. See:
https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp4-srv.html#shared-networks-in-dhcpv4
Example:
{
"Dhcp4": {
"shared-networks": [
{
"subnet4": [
{
// relays
"subnet": "10.1.0.0/21"
},
{
// client subnet
"subnet": "192.0.2.0/24",
"pools": [ { "pool": "192.0.2.100 - 192.0.2.199" } ]
}
]
}
]
}
}
