[Chilli] CoovaChilli Kernel Mode issue

[Xabier Oneca -- xOneca]

Hello Phyo,

module. http://lists.coova.org/pipermail/chilli/2010-April/001239.html

Yes, you're right. Sorry! I didn't know about kernel-module-specific
configuration quirks...

> Btw, when I looked at the syslogs, I saw the following lines when the
clients got the resetting issue.

the followings.

Maybe it has to do with your iptables rules. What rules are you applying?
