Refuses to Connect

I use a Sonicwall TZ appliance for my small business. In addtion to the appliance, I purchased 2 VPN client licenses. I currently VPN with my Windows laptop to my firewall, then use Remote Desktop to run on my Windows Server. I would like to do the same with my Mac. I have the Remote Desktop app since it came with Office, so all I needed to connect was the Sonicwall VPN client. When I saw it in the App Store I was excited. Boy, did my excitement quickly turn into frustration.

I can open and run the app, but at Add Connection I get: ‘xxx.x.xx.xxx is either currently unreachable or is not a valid SonicWALL appliance. Would you like to save this connection anyway? I triple checked the address and connected with my Windows machine just to make sure everything was working. I tried and tried to connect, but to no avail.

I do not see any reason why I would be unable to connect, but I cannot.

This app does not work.
