Hello, I am new to OpenVPN. I have been stuck with configuring OpenVPN Server for my Windows Server 2019 data center for over a week. I have also configured NAT in Routing and Remote Access and Firewall too. The client device is also Windows. I don't know what is missing because client's IP address is not changing. I have attached some info about the server and client. Can I get some help? Thanks.

Ok, it's weird but I think the problem is related to how Windows handle Network config. First, exit OpenVPN GUI or related processes. Then disable NAT config in "Routing and Remote Access" if enabled before. Re-enable NAT. Then start OpenVPN GUI as administrator. Now client connection uses the server's public ip successfully. Previously, I was doing NAT config after I had started OpenVPN GUI.
