Hmm..... wireshark configured to only trigger for udp ports 67-69

Luckily the local FreeGeek outlet had a 10/100 hub in stock

http://freegeekvancouver.org/

With wireshark running on my laptop, laptop hooked up to hub, hub hooked up 
to router dmz port, and mvp hooked up to hub, I see ZERO tftp traffic in 
wireshark, just ports 67 and 68 traffic, there is no attempts by the mvp to 
contact the tftp server on the other subnet, broadcast or unicast.  All I see 
are the dhcprequest and dhcpoffer packets.

Next configured wireshark to only show attempts to contact the ip address of 
the tftp server. That brings up more interesting info, now I see arp packets 
from the mvp asking who has 10.11.12.14 (tftp server on main lan).

That got me to doing some reading about proxy-arp

http://docs.forticare.com/fgt/techdocs/FortiGate_CLI_Reference_01-30007-0015-
20081105.pdf

The following added to the router seems to have done the trick

config system proxy-arp
edit 1
set interface dmz
set ip 10.11.12.14
next
end

This works, mvp loads up and I am able to access my backedn

Then.....

config system proxy-arp
edit 2
set interface wlan
set ip 10.11.12.14
next
end

The system barfs at this point saying there is a duplication in addresses, so 
I remove the dmz config, and run the proxy-arp command for the wlan only, 
hookup the mvp to my dd-wrt running wrt54g wireless bridge and it doesn't 
work, well at least I am half way there.

Will report back on that solution shortly.
