A、The TCP connection that matches the defined ACL will be reset by the router if the connection does not complete the three-way handshake within the defined time period.

B、The router will reply to the TCP connection requests. If the three-way handshake completes successfully， the router will establish a TCP connection between itself and the server.

C、The TCP traffic that matches the ACL will be allowed to pass through the router and create a TCP connection with the server.

D、The router will intercept the traceroute messages. It will validate the connection requests before forwarding the packets to the inside network.
