[Click] issue with kernel level click and connectivity

[abs6@njit.edu]

Hello All,

I have a simple kernel level click router configuration with two interfaces
generated from make-ip-conf.pl. The topology is like
LAN1---R1----R2---LAN2

When I run the click router (R1), I cannot ping from machines on either side of
LANs to each other.

Using dmesg following messages are observed:
click: starting router thread pid 3178 (eb0f3a40)
e1000_poll_on
e1000_poll_on

Initially, I thought my problem is similar to the problem with the arpqueurier
in the make-ip-conf.pl script discussed below on the click mailing list long
time  back, but I assumed it is fixed.

If anyone can help that will be great.

Thanks.

Amey
