[gPXE] arp proglem

[何闯]

Dear all,
 
This problem is as bellow:
192.168.1.3 and 192.168.1.2 are two bootloader client, form some reason, I need them to communicate with each other via UDP protocol.
However, 1.3 to 1.2 UDP packet invokes ARP transsmision,FIVE seconds have past before 1.2 receive 1.3's ARP request, resulting in a UDP sending timeout.

192.168.1.5 is dhcp & tftp server, seems that 1.5 communicates with both 1.3 and 1.2 are OK. What's wrong here?
 
 
yours,
soforth
