Hello Kiko,
Could you try adding adding below Line to dhcpd.conf file
option 1: DHCPDARGS="eth0 eth1";
option 2: INTERFACES="eth1 eth2";
To make permanent changes you have add to dhcpd.conf.templet file
bye the way i have not tested these settings but these config options are unix style for dhcp server to listen for specified interfaces.
Regard's

This configuration make no sense IMHO.. The GREEN it's a bridge so it's not necessary to add the interfaces by edit the dhcpd.conf.tmpl
Just check if the interfaces are added into the bridge with "brctl show"
