to understand --tcp-flags

["Ralf Braga" <ralf@xxxxxxxxxxxxx>]

Hi,

I dont understande this command:

iptables -A INPUT -p tcp --tcp-flags SYN,ACK SYN,ACK \
-m state --state NEW -j REJECT --reject-with tcp-reset

Because two times is used --tcp-flags SYN,ACK SYN,ACK ?


This example will be bloqued packages for flags syn and ack ?

Thanks,
