Thanks for the hint.
I had indeed set the rtp-ip to the fqdn of the server in internal.xml,
as this way I got rid of one way audio for internal calls.
Calls through external gateways didn't work though due to the error we
are talking about here.

Now I added a
<param name="ext-rtp-ip" value="stun:stun.freeswitch.org"/>
entry to internal.xml and external.xml in the SIP profiles and now the
RTP stream via internal and external profile is o.k.

I added a new chapter "Freeswitch behind NAT" to the wiki, where I
describe my settings:

Best regards
