reject an IP with Apache2 and Suse Firewall.

Hi, I'm getting some strange logs, in the apache access file from some IP's. How can I make a "blacklist" with apache so that I reject this specific IP from the webserver??? I'm wondering for the same thing in the Suse Firewall. How can I make a blacklist for the suse firewall??? This blacklist could be a simple IP list or ... maybe something more advanced can be made???
