The application that's causing the reset (identified by port numbers) should be investigated to understand what is causing it to reset the connection. If the incoming segment has an ACK field, the reset takes its sequence number from the ACK field of the segment, otherwise the reset has sequence number zero and the ACK field is set to the sum of the sequence number and segment length of the incoming segment.

A2: Once the connection is established, all packets need to have ACK set and match the sequence number of the received packets for reliable transport/security. RST without ACK will not be accepted. ACK - this is a packet with a receipt from the target acknowledging that the packet has arrived. FIN - Part of the TCP, a flag that tells the connection there is no more data to send. ICMP - variety of uses, often the Time To Live, which counts the number of 'hops' for a packet between routers, to ensure you don't end up in aimless circles.
