The iptables are stopped, whenever i tried to send packet with scapy i'm getting the packet is getting
RST after SYN/ACK
the iptables are stopped,
the packet are send from MACOSX to Linux OS
This is probably an RST packet sent by the MacOS IP stack.
You can use a firewall on the MacOS computer to prevent the IP stack from getting the SYN-ACK packet.
