[Firehol-support] FireQOS: Match to IP range

[Tsaousis, Costa]

Hi Brian,

You are right. I have done nothing for IP ranges.

However, since the config is a BASH script, you have many alternatives:

1) use a loop:

for x in {50..60}
do
   match src 10.10.10.$x
done

The above is not optimal though. If you give it 200 IPs, it will
produce 200 matches.

2) use iprange - the optimal way

If you have the latest version of firehol, there is a tool called
iprange in the contrib directory. Install it (cd contrib; make
install).

then you can do this:

match4 src "$(echo "10.10.10.50 - 10.10.10.60" | iprange)"

This will produce only 4 matches for:

10.10.10.50/31
10.10.10.52/30
10.10.10.56/30
10.10.10.60

Not a subnet, mind, a range of IP's, say from 10.10.10.50 - 10.10.10.60.  While I could match on each IP address in the range with the following:
> match4 src 10.10.10.50match4 src 10.10.10.51....match4 src 10.10.10.60
