Hi to all, I am able to start correctly openser, using mysql for authentication and user location. Then, I would configure redirect, but I don't know how. I have this situation: Internal network behind parallel NAT (any port open) Possibility to have a public IP Users should authenticate on openser, to being redirect (or forwarded ?) all to a single SIP provider, using the same credentials. As you can see, I an not clear if I have to use redirect or forward (I suspect forward). Is it possible ? Can you help me, suggesting also a possible configuration ? Thanks to all. Valerio
