since 2 months I am trying to set up a working ser.cfg for the following  
situation:

   private network        |        public network
                          |
      172.16.0.0/22       |
                          |
                    +------------+
              .1/22>| firewall/  |< 111.222.333.444
                    | router     |
                    +------------+
                          |
                          |
                    +------------+
                    |    SER     |
              .5/22>|     +      |<111.222.333.555
                    |  RTPPROXY  |
                    +------------+
                          |

The purpose of this situation is to insure QoS for VoIP service
host using standard internet service is routed via 172.16.0.1 router
when using a VoIP service, all SIP and RTP/RTPC messages should flow
via 172.16.0.5 Sip Proxy
Does anyone have a working configuration for such a situation ?
