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

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 :) )

Thanks! I found out, that in SuSEfirewall2-custom, I can use Shell skrips and variables. That does it!

Good luck :)

Hello List, I want to enable several (ten) hosts to access my VPN. I am using

SuSEfirewall

...

and I have custom iptables rules in SuSEfirewall2-custom. Now i want to add one rule for all these hosts. I know that "!" is the wildcard for "any host but the following". How can I add an iptables rule affecting Source IPs from e.g. 1.1.1.10 to 1.1.1.20? I've been looking, but i didn't ind something. Can I use bash-constructs like for.. in SuSEfirewall2-custom? Is there any docs around about this specific file? thanks!
