| Abstract: | A method for operating a firewall includes: in response to the firewall receiving a TCP SYN request packet that is sent towards a first node from a second node, said TCP SYN request packet comprising a sequence value ('seq'), sending to the second node a SYNæACK packet, said SYNæACK packet comprising a seq and an ack_ sequence value ('ack_seq'), where ack_seq of the SYNæACK packet is not equal to the TCP SYN request packet's seq+1; and in response to the firewall receiving a TCP RST packet from the second node, verifying that the seq in the TCP RST packet matches the ack_seq of the SYNæACK packet and, if it does, designating the connection with the second node as an authorized connection. | |||||||||||
