DHCPOFFER not being sent out

Hi all,

I have compiled and installed the latest ISC DHCP server software onto a
Sun Solaris 10 machine but am having issues with it not handing out IPs.

It is a simple configuration and running the server in the foreground
shows that client requests are coming in and offers are going out:

DHCPDISCOVER from 00:0e:7b:3e:cc:04 via eri0
DHCPOFFER on to 00:0e:7b:3e:cc:04 (laptop) via eri0

However the offers are not being picked up. More worrying is that when I
run snoop on this interface I can see the DHCPDISCOVER packets coming
in, but no DHCPOFFER ones going out even though the server claims that
it is sending.

Has anyone come across this before and/or do you have suggestions for
how I might debug this issue?
