Ans to part 1:
TCP uses a port. A port is identified for each address and protocol by a 16-bit number, commonly known as the port number. The port number, added to a computer's IP address, completes the destination address for a communications session. That is, data packets are routed across the network to a specific destination IP address, and then, upon reaching the destination computer, are further routed to the specific process bound to the destination port number.
So,a copy of the old FIN will not be able to terminate the new connection as port number in new connection will be different.
Ans to part 2:
No, a router can not send request to another router for TCP connection?
Reason:
TCP connections are for communication between applications but routers do not run applications.
