Hi im just wondering if you would be able to help me with the following.
Im trying to make a download limit on the forward chain so that when it has hit 100mg it will stop all my traffic on the lan... to stop getting internet access. But even when i try and use your rule below im getting cant load match.. 
Thanks for your help
Regards Tim

iptables -A INPUT -p tcp --dport 80 -m quota --quota 52428800 -j ACCEPT
iptables v1.2.5: Couldn't load match `quota':/lib/iptables/libipt_quota.so: cannot open shared object file: No such file or directory

Try `iptables -h' or 'iptables --help' for more information.
[root@tb root]# quota quota
quota: User quota doesn't exist.

Or is they any other way i can make a rule so i cant download more than 100mg a day?
