DHCP relay on an embedded platform

[Roman Mashak]

Hello,
 
Searching in mailing list and bugtrack unfirtunately didn't help to find any useful information on the topic.
 
I have an embedded platform running Linux 2.6 and busybox-1.7, where I enabled DHCP relay feature, recompiled and installed successfully. But the relay seems not to work as expected; below is the network map and interfaces:
 
PC-----[vlan1 embedded device vlan2]-----DHCP-server--
 
Embedded device with two interfaces:
vlan1 192.168.2.10  LAN
vlan2 192.168.1.1
DHCP server (192.168.1.150) is located on vlan2 segment. No dhcp daemon, only DHCP relay on the device is being run as:
 
# /usr/sbin/dhcprelay vlan1 vlan2 192.168.1.150
 
Windows PC runs DHCP client, sends query, and I capture traffic on vlan2, but see no DHCP activity (though I believe the box should aat least send one unicast with source IP 192.168.1.1 to destination 192.168.1.150).
 
Am I doing something wrong, or the relay daemon in this particular busybox version is faulty?
 
Would very much appreciate any comments and helpful advices!
 
 
Best regards, Roman
