Option to respond with a different pool in Freeradius DHCP based on interface

[Durand fabrice]

Hello Nataniel,

i worked a little bit on freeradius dhcp for another project and i did 
something like that:

listen {
     type = dhcp
     ipaddr = 0.0.0.0
     src_ipaddr = 192.168.0.1
     port = 67
     interface = eth0
     broadcast = yes
     virtual_server = dhcp.eth0
}

listen {
     type = dhcp
     ipaddr = 0.0.0.0
     src_ipaddr = 192.168.1.1
     port = 67
     interface = eth1
     broadcast = yes
     virtual_server = dhcp.eth1
}


server dhcp.eth0 {
  dhcp DHCP-Discover {
....
}
server dhcp.eth1 {
  dhcp DHCP-Discover {
....
}

A listener per interface and a virtual_server for each interfaces.

Regards
Fabrice
