从客户端而不是前端服务器获取IP地址

Question

I have a WEB API that has a backend in C# (using DDD) and a frontend that uses it in Angular hosted in different servers. I want to get my client's IP when they log in (for audit purposes), when I try to run my code through postman it works but when making the request through the frontend, it always return the frontend server IP.

I have tried using IpPublicKnowledge which is a Nuget package that gets the IP using a webpage.

I have tried different ways that get the IP from the HttpContext but they also return Frontend server IP, not the client's IO.

Answer 1

I am answering this in case anyone wants to know, I tried to get the IP through HTTP_X_FORWARDED_FOR but it wasn't reliable enough. So what solved it was to create a php server that got the ip from the client and have the frontend application use it and send it to the backend. @Chetan Ranpariya also said this and it ended up being my last resort.
