Why, due to NAT, the OpenVPN script does not see the public IP, only the local one?

Question

openvpn

I use Amazon aws and it was here that I ran into this problem, that the script writes "a problem with the nat server", and I prescribe a public IP and the script itself determines the public IP, but when connected to openvpn in the logs, it shows that a private (local) IP is used. OS Ubuntu 20.04. How to solve this problem?

Answer 1

Use elastic IP address for open vpn server in amazon!

Answer 2

Elastic IP use
