I am doing an installation of OCMS 10.1.3.4 on Redhat Linux 5 , with Oracle Database 188.8.131.52.0 at the backend .
The Server has a single Network Interface (IP) ie Public IP .
While installation the application is provided with all the necessary info Primary IP , Database details etc...
Finally when it comes to STUN installation , it asks for Primary and Secondary Host Address along with the port details.
Can someone explain me
1) What is STUN and how it works ?
2) How can I have communication among users from Public and Users behind the Firewall using STUN ?
3) What ports need to be provided for STUN Primary and Secondary ?
4) Will I require a Private Interface (Private IP ) enabled for users behind the Firewall?
