迅雷与攻击检测与防护设置

comodo防火墙高级设置里有攻击检测与防护设置，里面的TCP洪水攻击UDP洪水攻击ICMP洪水攻击，是可以吗？会不会限制迅雷的下载速度？如果要改大一些的话，要改为多大？

个人防火墙防御洪水攻击的效果很差,而且对个人用户进行洪水攻击意义很小,所以这个功能用处真的很少~
他不会影响迅雷的下载速度,迅雷下载过程中主要使用TCP
官方对于这个tcp防洪水的解释是:
Flood attacks happen when thousands of packets of data are sent from a spoofed IP source address to a victim's machine. The victim's machine automatically sends back a response to these requests (a SYN packet) and waits for an acknowledgment (an ACK packet).  But, because they were "sent" from a spoofed IP address, the victim's machine will never receive any responses/acknowledgment packets.
也就是syn洪水攻击.迅雷下载时候的连接行为和syn洪水攻击一点也不一样,所以comodo的这个功能不会影响迅雷的速度
