A pre-boot server address relay device relays packets from the diskless computing device to an address allocation server to discover available network addresses. The pre-boot server address relay device receives offer packets from the address allocation server offering a network address and generates modified packets by modifying each of the offer packets from the address allocation server. The modified packets are transmitted to the diskless computing device. The pre-boot server address relay device relays request packets from the diskless computing device to the address allocation server. The pre-boot server address relay device receives acknowledgment packets from the address allocation server acknowledging the request of the network address and generates modified acknowledgement packets by modifying the acknowledgment packets from the address allocation server. The pre-boot server address relay device transmits the modified acknowledgement packets to the diskless computing device to enable remote booting.
