[Serusers] ser and overlay networks

SER Crew: I am trying to use SER with an overlay network. SIP UA SER 12.34.56.78 -> 12.34.56.79 10.0.0.1 -> overlay network The configuration above is local side of such a configuration. The 10 addresses on the SER server machine represent the entry into the overlay network. The SER server has to proxy all traffic in and out of the overlay. I have tried some configurations using nathelper and rtpproxy. Using nathelper seems a little odd as there is no NAT problem here. I was hoping some one had a configuration file for this sort of hardware configuration. I have gotten some rtpproxy traffic to work between a couple of machines and I am getting the c= error. I'll pull fresh source from the CVS site. Thanks, Doug
