The netblock range, or something else?
Thanks to all that helped, especially for the very cool tool. You guys were right, it was "4.41.0.0/16 that I wanted to filter out. Seems it was not doing its thing because of where I put the rule in reference to the other ipchains rules. Just like in snort, it makes a difference. Thanks, -- J.
