Hi,
you can define a rule like that: iptables -A FORWARD -s 192.168.235.43,192.168.235.46 -d 10.0.0.1,192.168.0.1 -j ACCEPT it will create 4 rules. be sure to activate Networking support->Networking options->Network packet filtering framework->Core Netfilter Configuration->iprange address range match support Now you can do something like iptables -A FORWARD -m iprange --src-range '10.0.0.1-10.0.0.44' -j ACCEPT hope it helps -Stefan On Mon, Apr 05, 2010 at 07:32:17PM +0200, Jarry wrote: > Hi > > I'd like to ask if there is some way to include multiple discrete > hosts/IP's in --source and --destination options of iptables. > > I'm trying to write firewall rules for my server, but it has > 12 IP's from different segments (and maybe it gets a few more > later), and the script grows up as I have to write nearly > identical rules with difference only in -s/-d IP's. > > What I'm looking for is a way to define some variable at the > beginning of my script, like MY_IP="IP1 IP2 IP3 IP4..." and > later to use is in rules (iptables -A INPUT -s $MY_IP...). > But I do not know how to use it.
