TCP Service forward original IP

Traefik Traefik v2
,

I am using traefik with adguard behind it using DNS over HTTPS and DNS of TLS on a remote server. So I can use android "private dns server".
But what traefik does is forwarding the local ip instead of the outside IP. So I see the adguard log the docker IP of traefik. Is there away to forward the original IP?

Traefik does not "forward" the local IP, but the connection to Adguard has Traefik IP just as origin, because that's where the local connection is coming from.

Traefik will "forward" IP information by placing them in the HTTP header ( X-Forwarded-*), I think that's done automatically, check if Adguard supports getting the IP from the header. Alternatively you can check if Adguard supports proxy-protocol.

Thanks for your information, adguard does support x-forward-* since I was using SWAG before which was forwarding the IP just fine.
