[dba-Tech] Extranet VPN for testing customers' web sites/web API solutions

[Salakhetdinov Shamil]

Hi All --

I have a hosted on a cloud MS Windows Server 2012+ VM and I'd like to setup my customers' testing web sites/web API solutions.
The hosted VM has its own IP but I'd like to virtualize access to customers' testing web sites by using virtual IPs, which, as I expect could be provided by a VPN infrastructure/software.

For example via VPN:

1. Customer #1 would get access to virtual IP 15.27.103.185 referring real IP:Port  123.17.82.45:2337
2. Customer #2 would get access to virtual IP 15.27.103.142 referring real IP:Port  123.17.82.45:2338
...
N. Customer #N would get access to virtual IP 15.27.103.1147 referring real IP:Port  123.17.82.45:2399

(all the IP addresses and ports above are just sample ones not having any real refs) 

Is it possible?

If it's possible what software would you recommened to setup on server side? 
This one looks good - https://www.softether.org/1-features ?

I'd prefer free/not very expensive solution on server side and free solution for client/customers side.

NB: I currently prefer to not use MS Azure, AWS etc.

Thank you.
