How to make a self-service system?

Question

linux

Hello, they offer to make a website for a small Internet provider.
I would not mind, only they need a personal account of the client, but I have not come across this.
How do providers store subscriber data, and how to pull it out for display in your personal account?
Knowledgeable people please help.

Answer 1

There are certified billings for this.

Answer 2

You need to ask your provider for this.
Or do it first without integration.

Answer 3

1. REST API to the base of the billing system
2. Web-face (frontend) on includeHTML (interface of dynamic blocks with different markup for each type/menu item and data to display)

Answer 4

GW1 should have a route to network 10.145.22.0/24 pointing to GW2 (192.168.0.1).
