Re: Dynamic firewall based on bandwidth usage ?

So I have to block (or redirect) those
network abusers after a download limit (for ex : 1Gb per day)
for lets say 1day.

iptables -A INPUT -p tcp --dport 80 -m quota --quota 1073741824 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP

With the IPtables-quota how do you block this IP for a given time?
And what does the 'leecher' prevent to change the IP address?
When I scent that there could be a limit - I would disconnect my DSL
and continue downloading with my new connected IP.?!
But I also don't have a better idea...

Kind Regards,
