isc-dhcp-server (4.3.4-1) en Stretch con problemas

Buenas Noches a todos, les traigo una nueva duda a todos, anoche en una locura decidi pasar el server de casa de 8.4 a la furuta version 9.

Me encontre con muchos cambios entre ellos abandonar la rama 3.1* del kernel linux para arrancar con 4.5*

isc-dhcp-server incormpora dhcpd6.conf para redes IPv6 y si el mismo fichero no arranca.

Lo raro aqui es que la configuracion vieja deberia funcionar en IPV4 segun tngo entendido, es mas al arrancarlo nos da todo OK y el status nos da OK, pero no atiende ninguna peticion, alguien tiene idea que puede ser??

Config dhcp.conf
