DoH and client authentication

Posted

I’m trying to use my own DoH server with Firefox. It works fine basically but if I enable client authentication on it, DoH seems to fail. Since It’s difficult to create ip address based access filtering for remote mobile users, I want to add some user authentication feature to my DoH session.

Does current DoH client of Firefox support “TLS client certificate” or “HTTP header” authentication?

2. Regarding HTTP header auth, DoH server (nginx on frontend) generated logs something like "no user/password was provided for basic authentication"....


Does anyone have tried to authenticate Firefox DoH user to prevent your DoH server from being an open resolver?

Is this something your own making or from whom software/hardware are you using this from? If not yours did you contact their support on this issue since firefox AFAIK isn't a server software?
