This article would be the second part of OpenSIPS 1.11.6 installation on Ubuntu Server 14.04.
The first part available here. It is recommended to read and follow the first part first.
There are 2 sections available in this part:
- OpenSIPS NAT Configuration
The focus on this part is to setup a way to help User Agents under NAT routers. No user authentication stuffs will be added, for that you will need to also follow the instruction on part 3, when its available (soon).
Let’s do the 2nd part.
