WHAT IT DOES
What does it do?
i-server uses the IP addresses of the real server alongside those of multiple third-party servers, making it difficult to distinguish the real server from client traffic alone. It uses Echo Reflection when NAT does not change the ICMP identifier and Destination Unreachable when it does. In the former case, data is relayed indirectly through Echo Replies generated by third-party servers.
