FW dropping ACK, RST/ACK & FIN/ACK packets though packets are from valid sessions

Jim Tagert
Does the ASG function in this manner?

When the firewall receives a TCP RST for an existing session it immediately clears the session from the session table. This means there is no longer a valid session for the TCP RST/ACK to pass through. Hence, the firewall will treat the TCP RST/ACK as a non-SYN first packet and drop it.



Thanks,

Jim
