Hello everyone,

Should I use a STUN server, or can I just configure NAT properly?

Here’s my current setup:

arduino
Copy
Edit
Router (NAT device)  
   ↓  
Kamailio + RTPengine machine  
   ↓  
Virtual machine running Kubernetes  
   ↓  
Asterisk container
Kamailio and RTPengine are sitting behind the NAT (the router), and they handle SIP and media. Do I need a STUN server in this case, or can I manage everything with NAT configuration alone?
And what is the better approach?

Any insights or best practices would be appreciated!
Thank you.
