DHCP Across Wireless Bridge

Hi Ted,

The web interface of the wireless bridge I'm using (an EnGenius EOC1650 
in client bridge mode) is fairly basic and is very limited outside of 
WLAN options.  However, I can telnet into the device.  It is running 
BusyBox 1.00-pre10.  Perhaps I can modify it somehow to add option 82 to 
DHCP traffic?  I'm not sure...

It's not a discussion for this list, but if anybody has any experience 
with BusyBox and this I would love to learn about it. :-)
