iptable Mark packet and use this mark in other rule


Hi, all
I'll like to mark all packet coming from and going to an ip adresse. And I'd like to match that mark packet in an other rule.
Ex :
Rule 1 : Mark all packet coming from 192.168.2.0/25 with number 1
Rule 2 : Drop all packets which has been mark with number 1

How could I write these tow rules.
Regards.

example:
Code:
iptables -A PREROUTING -t mangle --match mark --mark 1 -j ACCEPT
iptables -A PREROUTING -t mangle -i eth1 -j MARK --set-mark 1
or you can use chains rather then mark.
or -m recent
