Yes. Traffic will be recognized by the firewall and must be allowed by opening a certain port over TCP/UDP (though this process will be automated with the script). VPN tunnel traffic is encrypted with symmetric key using AES-256-CBC algorithm and RSA algorithm is used for key-exchange process.

After I used this script, the server IP was blocked and the location was in China.

It doesn't make sense. IP location depends on where your server is located. Script does not perform any operation on IP manipulation. IP address must be the public address of the server where the script is being executed.

I just tested on AWS EC2 instance, everything working fine.

I'm referring to the IP being blocked, the VPN detected.

OpenVPN does not have stealth/obfuscation...the application signature can be detected by firewalls. Forget this with China and Iran.
