Okay, dhcp-relay is working fine for any pc device, just not for the mvp.

Reading some of the wiki and previous list postings seems to indicate that 
the mvp ignores the next-server declaration in the dhcp lease, is that 
correct.  I got slightly confused in my reading about that as it seems that 
specifically applies to the H. series units rather than the older D3A's I 
have.

Further testing points to an mvp issue itself. Hooking my wife's XP 
workstation to the dmz port, allows it to get an address in the correct 
subnet from the dhcp server on the main subnet, So DHCP relay is working 
fine.

The problem seems to be with tftp and the mvp specifically as I can see that 
the mvp is getting an ip address as I see the dhcpdiscover and dhcpoffer in 
the logs, but don't see a dhcpack. Testing on the main lan indicates the mvp 
doesn't do the dhcpack UNTIL it's fully finished loading the firmware via 
tftp.

Hooked up my pda to the dmz subnet with a tftp client, I can successfully 
pull the firmware file across the subnets, so I know the tftp traffic can 
flow between subnets, so that's not the issue.

Just tried adding the "option tftp-server-name text;" declaration, but that 
had no impact on the situation, mvp gets ip, tries to load firmware, but 
never actually contacts the tftp server as there is ZERO traffice in the tftp 

server logs.

Note, I am using the isc dhcp server on CentOS 5.2.

# rpm - qa | grep dhcp
dhcpv6-client-1.0.10-4.el5_2.2
dhcp-3.0.5-13.el5

Suggestions?
