ASP.Net Core检测真实客户端IP

Question

I've got an ASP.NET Core app hosting on IIS, the server with which is behind the router. I need to detect real clients IPs. From the local network context.HttpContext.Connection.RemoteIpAddress returns correct IP, but from the outside it is always 127.0.0.1 .

Also I tried to look at X-Original-For header which locally gives 127.0.0.1 and nothing form the outside.

I tried UseForwardedHeaders ( https://stackoverflow.com/a/41450563/4801505 ) middleware but as I got it the middleware is already used by UseIISIntegration ( https://github.com/aspnet/Docs/issues/2384 ) so there is no sense using it twice.

So, can I achieve the thing at all in my circumstances? Maybe some IIS config required?

Answer 1

Use the external link to get ip address.

I end up using

 var httpClient = new HttpClient();
        var ip = await httpClient.GetStringAsync("https://api.ipify.org");

If you are using any language other than C# refer to website ipify
