Hello, I have a question on iptables. On the arch wiki, the tutorial on a simple stateful firewall includes the creation of the following rule. # iptables -A INPUT -p tcp --syn -m state --state NEW -j OPEN-TCP Which, to my understanding, meant only pass new TCP streams with the syn flag (the initialize connection or handshake part 1 of 3) to the user defined chain. When I checked the output of iptables, I noticed the following rule. # iptables -L INPUT --line-numbers -v 7 OPEN-TCP tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/SYN state NEW Why is iptables also using the FIN, RST and ACK/SYN flags? Did I not request SYN only like I thought the tutorial said? _________________________________________________________________ The New Busy is not the old busy.
