PXE boot port issue

Hi,all:
I want to boot an IA unix box from network, I am sure I set the DHCP and boot server, but it still failed !

It says : Client MAC Address: 00 18 FE 28 91 82 .....-
PXE-E16: Valid PXE offer not received.
Load of Core LAN Gb A failed: Not Found

I use the nettl command to trace the UDP package, it writes:

From the document, I got that the client port is 68, the server port should be 67, I mean the DHCP server listening port, while in the UDP package, it shows 4109.
Thanks !

NAME
burgerspace-server - UDP server for the networked version of BurgerSpace SYNOPSIS
burgerspace-server DESCRIPTION
burgerspace-server is a server that accepts connections from BurgerSpace clients to allow two players to compete with each other. One player controls the chef and the other controls the egg. Other clients can connect as spectators. burgerspace-server should be started in a terminal. To terminate it, give the Ctrl-C sequence or use the kill(1) command with the server's process ID as the argument. The connections use the UDP protocol. The --port option can be used to specify a non-default listening port (see below). After the server has started, the user who wants to control the chef must start the client with this command: burgerspace --server=the.server.hostname.com --chef Use the appropriate hostname or IP address as the argument for --server. The user who wants to control the egg must give the --enemy option instead of --chef. The --port option can be added to the burgerspace command-line to specify the server port, if the server was started with a non-default UDP listening port. OPTIONS
--help display a help page and exit --version display version information and exit --initial-level=N start game at level N. Default is 1. N must be at least 1. --port=PORT UDP port number on which the server must listen for incoming clients. The default is 49152. LICENSE
