    Passing DHCP traffic in bridged mode

    kdesnayer

      Anyone have a workaround to pass DHCP traffic while the firewall is in bridged mode....

       

       

      Windows VM ----> Sidewinder in Transparent mode -----> ISP DSL mdm -----> ISP DHCP server

      ^internal zone                                                               ^external zone

       

      I have a Windows host on the internal side making a DHCP discover request (Dst Port 67, DST IP 255.255.255.255, DST MAC ff:ff:ff:ff:ff:ff)

       

      I can see the packet appear on the bridge0 interface but it does not exit the external interface that faces the ISP as expected as I believe that the firewall will not just broadcast the DHCP request to all zones...
