Why does my Indy10 UDP server return a response being sent by a different IP?

Why does my Indy10 UDP server return a response being sent by a different IP?

Here's a step-by-step guide in words:

Bind to a Specific IP Address:

Ensure your UDP server is configured to bind to a specific IP address rather than any available address. This prevents the operating system from choosing a random IP for sending responses.

Check Your Network Configuration:

Verify your network settings to ensure the server is set up correctly. Sometimes, network configurations can cause responses to be sent from a different IP.

Review Firewall and Router Settings:

Make sure your firewall or router is not causing the issue by rewriting or redirecting traffic. Incorrect settings might cause responses to appear as if they are coming from a different IP.

Update Your Code:

Although you asked for no code, it’s worth mentioning that in a typical scenario, ensuring that your server correctly binds to the specific IP address you want to use is crucial.

Consult Documentation:

Look at the Indy10 library documentation or forums for any known issues or additional configuration tips related to UDP servers.

Test in a Controlled Environment:

Try running your server in a controlled test environment with minimal network complexity to isolate and identify the problem.

If you follow these steps, you should be able to address the issue of your UDP server sending responses from a different IP.
