Hi John

I tried it TWICE, it didn't work. For the time being TWO HOSTS are involved. 
I can ping between two machines through wireless interface , it is working 
fine with both running on " click configurations"

GATEWAY NODE:
./conf/gen_config_roofnet.pl --dev "wlan0" --gateway 1 > /click/config

/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

-------------------------------------------------------------------------------
I am trying to ping the eth0 interface (153.90.196.45)of the GATEWAY 
machine!! it didn;t work. Something is wrong in my configuration?, i 
followed as suggested by you. I mean as far i understand it should work.

Some more hints?? i guess.

Thanx for all help.

Gaurav
