i saw earlier that in kernel 2.6.23.1, there isn't the iptables modules. before, i tried OZ, angstrom (and other distros)... never there was iptables-modules.
my zaurus, as it is a very mobile computer, may be very often facing the wifi attacks from wifi, both on the internet, and in my university-campus.
The question is : how do you guys set-up a firewall right now ? is there a way ? or nobody has one and nobody care ? don't you guys think it could be a "plus" to be able to launch iptables when our zaurus comes on an untrusted network ?
