The double nat scenario is going to be a fun one to solve.  You're better off putting FreeSWITCH on a public IP or fully understanding what is going on.  

The outbound profile isn't for inbound registrations by default.  Its almost what you need but you'll need to turn auth-calls=true and you might need to force the registration domain.  Do you have phones behind that nat with FreeSWITCH registering to port 5060?

<param name="force-register-domain" value="cluecon.com"/>  <-- force the domain on a sip profile.

Could any of you share your experience with remote SIP extensions behind another NAT?

Basically my setup whould be like this:

[ Remote SIP extensions]------>(private IP@) NAT Router B---(public IP @B)-------(Internet Cloud)-----------(public IP @A)  NAT Router A---(private IP @A)------(private IP@C)[Freeswitch]

I have the domain registered as "sip.mydomain.com"


let's see, I am trying to config the remote SIP extension as 1018 using port 5080 hitting the public context, but I got the error on the freeswitch console

"user 1018@sip.mydomain.com not found"

Could you guys guide me to the right direction for remote SIP extensions' deploymen?

Your helps are appreciate.
Thanks,

Chris
