Here is a method I use to frustrate people trying to
nab my wifi connection using iptables (wireless router
-> linux router -> dsl -> net). The wireless router in
setup with a basic NAT for my desktops and wireless
but the wireless comes in on its own nic. with
prerouting set to drop, I have
[1:56] -A PREROUTING -m ttl --ttl-eq 202 -j ACCEPT

echo 204 > /proc/sys/net/ipv4/ip_default_ttl
on my laptop init
