I'm beginning to understand why you've made your choices. Just for reference, I've also found the info on the CHAOS target here (http://jengelh.medozas.de/projects/chaostables/) to be helpful. I am still unclear about some of these 'other' invalid mask/comp pairs I see ... For example, SYN,FIN,RST,ACK,URG,PUSH,ECE,CWR FIN,URG,PUSH Is this pair already included as a subset of your 36 invalid combos? Or is it yet something different? --JC -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
