Well.. try it.. if it works - it accomplishes that what you wanted! Right?
I am a little bit paranoid so all my policies are set to DROP... and in the
chains I control what gets in/out/forwarded...

To be sure that IP's don't get hijacked and that nothing from the WLAN
gets through, I also added:
iptables -P FORWARD DROP
iptables -I FORWARD -i ppp+ -j ACCEPT

It works; does this accomplish what I want?
