Hello Gargi,

your setup looks correct from what you've pasted. Some questions to find
the reason:

1. Have you set "up" all the interfaces by doing "ifconfig <dev> up"? 

2. If you set IPs on br0 of open-mesh1 and br0 of open-mesh2 manually, 
can they ping each other? 

3. If yes (and configured within the subnet of PIX): 
Can you ping PIX from open-mesh2?

4. If you do udhcpc on open-mesh2, do you receive the packet on br0 on
open-mesh1? Please check with tcpdump, this should work. If yes, do you
also receive it on the PIX? (Maybe the answer is getting lost somewhere).

BTW, i've set up similar scenarios yet, this is supposed to work. ;)

best regards,
	Simon
