TCP (RST ACK)

Hi All,

Please advise on the below. I checked and RST-ACK is like FIN-ACK to close the connection..

Question:

1)Without the (Fin-ACK) from 10.1.1.2, can 10.1.1.1 send (RST-ACK)?

2)If the above is yes, should 10.1.1.2 send (FIN-ACK) after (RST-ACK)?

Say the TCP session is between 10.1.1.1 and 10.1.1.2

10.1.1.1---->syn 10.1.1.2

10.1.1.2---->syn-ack 10.1.1.1

10.1.1.1---->ack 10.1.1.2

------Omittied the data transfer-------

10.1.1.1 -->RST,ACk 10.1.1.2

Thanks
