Using IP Helpers

If you are using IP Helpers to direct your PXE traffic then your routing hardware should be configured to redirect DHCP Requests to both your DHCP server and to the 2PXE Server. The PXE Boot request will be picked up and processed directly by 2PXE Server. The request package contains all of the information required by 2PXE to ascertain the hardware type and machine identification in order to ensure that the correct boot information can then be sent to the requesting client.

If you are using IP Helpers then the rest of this DHCP Configuration section can be skipped as it only applies to environments that are using DHCP options to handle PXE boot requests.
