Just posting my solution - maybe helps someone here ...
Host:
rtpproxy -l <public IP> -m 35510 -M 37790 -s udp:10.1.1.1:12500 -n
tcp:10.1.1.200:12500 -d INFO:LOG_LOCAL1 -i -u rtpp:rtpp
Client (Guest)
opensips.cfg <snippet>
# Modul
...
loadmodule "rtpproxy.so"
modparam("rtpproxy", "rtpproxy_sock", "udp:10.1.1.1:12500") # CUSTOMIZE ME
modparam("rtpproxy", "rtpp_notify_socket", "tcp:10.1.1.200:12500")
...
# routing
...
rtpproxy_offer("nro");
rtpproxy_answer("nro");
...
----
Runs good except of UA Client (WLan - Android CSipSimple/Keyyo-Voip) <--> Server
Here i have after random time connection loss (rtp) ... maybe WLan, but try to
figure it out
Greetings
Jens

Rtpproxy works just fine out of the box behind NAT. There's no need
to patch rtpproxy to achieve this functionality.
There was a patch posted a while ago to achieve this functionality,
but the patch is not necessary:
http://opensips-open-sip-server.1449251.n2.nabble.com/Rtpproxy-behind-the-NAT-td5008041.html
All one needs to do is force the IP to be used in SDP via the second
parameter of rtpproxy_offer/answer function.
