ipfw configuration file.txt

[luzzo]

Hi, do you know if it is possible to set a series of IP addresses in a text file and use it in this way:

$IPF 90 allow all from 37.59.15.197,127.0.0.1,"file.txt" to any

If it is possible do you know how the right syntax must be in file.txt? And where is the path of file.txt?

Not related but you can use "lookup tables". Instead of a file, you can use a lookup table to save a large set of IP addresses, port numbers, etc. For example:

ipfw table 1 add 192.168.1.1
ipfw table 1 add 192.168.2.0/24

ipfw add 100 allow all from table(1) to any

Where "1" is table number. Please refer to ipfw(8)() for more information.

# IPs i want to block
exec < /etc/rc.ipfw_blocked_ip.txt
while read ip
do
        $ipfw -q table 2 add $ip
done

$ipfw -q add deny ip from table\(2\) to any in via $oif

The text file is just a simple list of dotted-decimal IP addresses, one per line.
