      • How do you get the client's IP address on the server application I have custom sinks running to provide encryption but I can't seem to find the right interface to implement so I can get the remote client's IP. I know I can have the client application simply send its IP in the headers but that doesn't help me when the client is behind a NAT device so I must rely on the server to provide it.
