[En-Nut-Discussion] DHCP on multiple interfaces?

[Robert von Knobloch]

      Sorry to intrude, but this may help. As the DHCPDISCOVER packet
      should contain the mac address of the client


      it follows that this packet cannot be 'broadcast' or 'routeed' to
      all adapters as Harald suggests,


      instead it should be broadcast (using 255.255.255.255 OR
      xxx.yyy.zzz.255 for the adapter's subnet - either are allowed per RFC)


      separately for each DHCP configured interface.


      From RFC 1541 <http://tools.ietf.org/html/rfc1541> Dynamic Host
      Configuration Protocol October 1993


      3.5 Use of DHCP in clients with multiple interfaces



   A host with multiple network interfaces must use DHCP through each
   interface independently to obtain configuration information
   parameters for those separate interfaces.


Best regards,
