How disable edns in doh-server

[shirakun]

Hi

I created a doh-server
But I want to use the server ip instead of the client ip when requesting the upstream dns
But I noticed that the doh-server seems to pass the client ip to the upstream dns.
How do I disable edns for doh-server?

If you have an Nginx frontend, simply removing X-Forwarded-For and X-Real-IP would be enough.
