Recommendation As data replication will almost always involve data ingress or egress beyond the local VPC, when installing Fusion on an EC2 VM, both the above resolution steps should be implemented by default.

Don't see what you're looking for? Ask a Question. Start by comparing the source trace and destination trace, you will be able to notice if there is a change in the packets itself or if any new packets are reaching the destination on behalf of the source.
In this case, you'll again need help from the network team to identify any device that's modifying packets or replaying packets to the destination. When you have identified that the resets are not due to retransmits or incorrect parameter or packets being modified with the help of network trace, then you have narrowed it down to application level reset.
The application resets are the ones where you see the Acknowledgment flag set to 1 along with the reset flag. This would mean that the server is acknowledging the receipt of the packet but for some reason it will not accept the connection. This is when the application that received the packet did not like something it received. In the below screenshots, you see that the packets seen on the source and the destination are the same without any modification or any drops, but you see an explicit reset sent by the destination to the source.
The application that's causing the reset identified by port numbers should be investigated to understand what is causing it to reset the connection. UDP is a connectionless protocol and the packets are sent unreliably.
You would not see retransmission or resets when using UDP as a transport protocol. When you have the UDP packet sent out on a port and the destination does not have port listed, you will see the destination sending out ICMP Destination host unreachable: Port unreachable message immediately after the UDP packet. During the course of troubleshooting connectivity issue, you might also see in the network trace that a machine receives packets but does not respond to.
In such cases, there could be a drop at the server level. To understand whether the local firewall is dropping the packet, enable the firewall auditing on the machine. You can then review the Security event logs to see for a packet drop on a particular port-IP and a filter ID associated with it. Now, run the command netsh wfp show state , this will generate a wfpstate. After you open this file and filter for the ID that you find in the above event , you'll be able to see a firewall rule name that's associated with this ID that's blocking the connection.
