Antony,

I solved the problem, I removed default "auto" from internal/external 
profiles, and set up:

<param name="ext-sip-ip" value="$${external_sip_ip}"/>
<param name="ext-rtp-ip" value="$${external_rtp_ip}"/>

Everything according Wiki page: 
http://wiki.freeswitch.org/wiki/NAT_Traversal



Just strange behavior:

When I press F9 in the fs_cli, I see strange value for "Ext-RTP-IP"

RTP-IP                  192.168.1.5
Ext-RTP-IP              stun:stun.freeswitch.org
SIP-IP                  192.168.1.5
Ext-SIP-IP              173.79.237.112

Line from vars.xml looks OK:

<X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/>

I assume, Ext-RTP-IP must be 173.79.237.112 - as same as 173.79.237.112.
