[Click] testbed setup using click

[Ashok Anand]

Hi,

I am a new user to click.
I am trying to setup a simple testbed using click.
so there is a web server and a client, and there are two intermediate nodes,
which runs click at userlevel.
First intermediate node, changes packet data, while second intermediate undo
the changes.

The problem that I am facing is that, the second intermediate node does not
find any changes in the packet.
Is it because, the click is running at userlevel, and modification at
userlevel, does not appear when sent to network..
(I am using simple configuration, which just reads packet from an interface,
changes it, and then sends to another interface).

Please let me know.

Thanks,
Ashish
