Re: [suse-security] iptables wildcard for IP Addresses?

["Arthur" <tuur@xxxxxxxx>]

Markus,

You could try something using your subnetmasker.
For example, if you use this prefix: 1.1.1.17/28 (subnetmask
255.255.255.240)
you are giving access to hosts 1.1.1.17 through 1.1.1.30

A subnetmask 'calculator' is very handy with these things.
I use a freeware package from Boson, I believe it's called ipsubnetter.
(Try to google it or something :) )

Good luck :)

Regards,

Arthur Kok
