Hi. I was reading about certain kind of attacks about TCP sequence and I was wondering whether iptables is vulnerable to theses attacks. Especifically, whether iptables is capable to know if a RELATED or ESTABLISHED package is sent with a sequence number prediction attack and whether iptables is capable to know if the IP address has been spoofed by these means. -- Andres Roldan, CSO Fluidsignal Group - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
