RAK VPN setup not working

Issue: Following setup instructions for RAK OpenVPN connectivity to 7240

Setup: Cloud instance on Digital Ocean - running Linux Ubuntu 20.4

LoRa® Server: N/A

Details: I followed directions from RAK Industrial LPWAN Gateway Remote Management - OpenVPN. After completing all the steps and trying to install Tap0 on the server - however, it does not show with the command ifconfig. I checked my setup and it all seems to be accurate. I want to be able to remotely access my 7240 for monitoring and provisioning.
