[Click] click router with grid

[Kaza, Krishna]

hi,

I am using the click router with grid elements over wlan0 interface.
Everything is working fine as long
as all communications are within the grid network. The moment i try to ping
any machine outside
the grid network nothing works. I did some debugging and found that the DST
mac address which
should be set to the gateway address is not being set. Instead its using all
zeros. 

Any clues anyone?

thanx,
krishna
