Does anyone have some pointers to creating a script that will forward DHCP packets to a EAC appliance in a layer 2 Network?

Correct,

Run a cable from the core to NAC's Eth1 port.

Then in NAC Manager click on the NAC --> Configuration Tab --> Click the "Edit" button under the interface Summary box

Even if the client authenticates to another NAC in the Appliance group and the DHCP request is seen on this NAC there is NAC to NAC communication to resolve and populate the information accordingly.

Hi

Thanks for the reply. So based on that, i could remove bootp off the core and simply extend all vlan's onto the NAC listening port?

As long as it's possible to extend each VLAN to the NAC's 2nd NIC it can listen on multiple VLANs. You're basically extending the broadcast domain for each VLAN to include a listening only interface on the NAC that will see the DHCP requests as they are broadcast packets.

Thanks

Problem is, we have multiple VLAN's that don't route.
