[Gllug] iptables question

[Adrian McMenamin]

I have a wireless network. I want to leave it open for certain things
but close it off for people, for instance, just randomly using it to
browse the web. Why does

-A INPUT -p tcp -m tcp -i wlan0 --dport 80 -j LOG
-A INPUT -p tcp -m tcp -i wlan0 --dport 80 -j DROP

Neither log nor block the traffic. Will an iptables firewall not detect
traffic being routed through it rather than at it (if you see what I
mean)?
