Hello,
what is ip 1.1.1.1 in your trace? I see you use it with advertise for
listen. In that case, you don't need set advertised address function in
routing blocks.
Few things that you should check:
- the listen on the dms address has to be with advertise of firewall
port forwarding public address
- the rtp relay has to advertise also the firewall port forwarding
public address
- you have to do rtp bridging -- I see you use rtpengine (or its former
version mediaproxy-ng). I think that doesn't have support of bridging
two ipv4 networks, you would need to run two instances, and bridge the
local interfaces via linux config. Alternative is to use rtpproxy which
can do bridging and you can force media ip to be firewall public address
via rtpproxy_manage() parameter or use a patch for adding advertised
address parameter to rtpproxy (I made one available at
https://github.com/miconda/rtpproxy/commits/master)
Cheers,
Daniel

Hi all, I need help configuring a little bit complex NAT/PAT scenario. Idea
is that clients on Internet registers themselvs against kamailio and then it
routes requests to Alcatel PBX. kamailio acts also as NAT proxy ( so that
clients on internet does not need vpn connection. Something like EDGE SERVER
for MS Lync clients)
Below the scenario
Alcatel PBX: 10.9.6.3
Kamailio internal NIC: 172.16.52.240
Kamailio DMZ NIC: 10.9.23.180
PU.BL.I.C.IP: 1.2.3.4

As you can see there is a firewall that make NAT and PAT from PU.BL.I.C.IP
to internal Kamailio DMZ nic.
natted ports are 5060 and range from 30000 to 65000 ( for RTP )
I'am tryng to use kamailio.cfg that comes with installation.. Now I am
making some changes but is not working.
Internal client ( lan 172.16.52.x ), registered on kamailio, can make call
to alcatel phones and viceversa.
External client ( on internet ) can register to kamailio but cannot call
alcatel phone nor client registered on kamailio.
