Hi all, i've got problem to use iprange with iptables... iptables -V : iptables v1.3.1 When i try : iptables -I INPUT -p tcp -m iprange --src-range 192.168.1.1-192.168.1.5 -j DROP I've got this error: iptables: No chain/target/match by that name but when it try : iptables -I INPUT -p tcp -s 192.168.1.1 it works perfectly... I've seen on the web that the iprange is built-in iptables... Moreover, when i try : iptables -I INPUT -p tcp -m iprange -s 192.168.1.1-192.168.1.10 -j DROP i've got this error message: iptables v1.3.1: iprange match: You must specify '--src-range' or '--dst-range' Try 'iptables -h' or 'iptables --help' for more information but when i try iptables -h, there is no information about iprange... Do you have any idea?? Is there a patch to apply in order to use iprange? Module to be load? Thanks a lot for your help! lm.
