Hey,
I’m trying to spin-up, in a semi-lab environment, a PBX for testing. When I asked my ISP for a SIP trunk (They also provides it), they said I’ll have to also get another IP address, to be directly assigned to the PBX, which I expected to be in the same range of my regular public IP, but to my surprise, I received an IP in the range of 10.57.0.x, which is a private IP, to my understanding. I know that they should be asked that question, but our relationship is… not very communicative.
For example (IP address made up for this post):
My gateway IP is: 33.80.87.119
My current public IP is: 33.80.87.118
The IP I was given for the PBX: 10.57.1.254
Is it possible that the private IP is used only for communicating between the PBX and their trunk, creating some sort of a local networks between us?
I noticed this guide, but I’m not sure it suits this case well: pfSense® software Configuration Recipes — Routing Public IP Addresses | pfSense Documentation
As I said, this is mainly for testing and I’ll be the first to admit it’s kinda of a hobby, and I’m learning as I go, so if something doesn’t makes sense here, I do apologize.
I appreciate your help. Thank you
