[Spce-user] sip:providerCE with public IP

[Isaak (Web-e-volution)]

Hello,

I have a public IP mapped to a private IP.
This private IP is configured within the VM (sip:provider mr3.5.1).

I have executed:
$ ngcp-network --set-interface=eth0 --advertised-ip=MY_PUBLIC_IPADDR
$ ngcpcfg apply


However, I am having the problem that the VM when connected to LAN, all devices connected to the same LAN can make and receive calls.
But when collocating the VM into public connection, the devices can connect to the server and make a call but the call cannot be answered.
Once the call is answered, it gets disconnected immediately.

What is it missing? I have all default ports open in the public connection.
