Do you necessarily require the auto NAT stuff? Perhaps you can try with FreeSwitchConsole.exe -nonat and then manually configure your router not to do anything silly with SIP traffic. Make sure you turn off any SIP ALG. The wiki has a list of some of the more popular routers and how to turn off the ALG:

Hope this helps.
