[Flexisip-developers] Front-end configuration guide?

I'm running bc-flexisip-1.0.10-222.el7.centos.x86_64 in front-end mode (or attempting to!).

 

I have my auth module properly configured and authenticating requests: 

 

I also have the register module configured to proxy to a back-end server and have the Route module set to my back-end server. On successful auth, flexisip is properly sending the register on to my back end server:

My problem is that the back end server (as it should) challenges this proxied register with a 407 and flexisip does not pass along auth. In the Auth module I have tried setting new-auth-on-407 to both true and false, but in neither condition will it respond to the challenge; it just feeds it back to my client (in this case the Linphone Android app), who ignores it.

How do I get Flexisip to properly respond to this challenge? Does anyone have a primer for setting up the front-end / back-end?
