[K12OSN] no response from dhcp server (eBox 2300SX)

[Nadav Kavalerchik]

i've got a new eBox 2300SX connected to the terminal server
(that works fine with different types of PC clients :-)

while booting i get stuck on the stage in which the client request a new IP
from the dhcp server.
they negotiate for a few seconds and the eBox client stops with
"error failed dhcp" (no response from dhcp server)

here is the log on the server side:
DHCPDISCOVER from 00:1b:eb:02:00:91 via eth1
DHCPOFFER on 192.168.10.253 to 00:1b:eb:02:00:91 via eth1
DHCPREQUEST for 192.168.10.253 (192.168.10.254) from 00:1b:eb:02:00:91 via eth1
DHCPACK on 192.168.10.253 to 00:1b:eb:02:00:91 via eth1

server is sending kernel to terminal and terminal loads ok :-)
just before switching to X i get this error from the dhcpclient
trying to get a new IP and not getting any from the server:
