[Spce-user] NGCP Behind NAT

[Andrew Pogrebennyk]

Hi Paul,

you can use our advertised_ip option. Please set it with ngcp-network
command like:
ngcp-network --set-interface=eth0 --advertised-ip=x.y.z.w

As far as I understood, you are going to advertise public IP and setup
port forwarding on your router. You will probably need to forward the
ports for rtp proxy, check the handbook for port range it is using or
options rtpproxy.minport, rtpproxy.maxport in
/etc/ngcp-config/config.yml or
/etc/ngcp-config/templates/etc/default/ngcp-mediaproxy-ng-daemon.tt2

Regards,
Andrew
