VPN to Bypass Port Forwarding Restrictions

Here’s my situation. My home Internet access is provided by AT&T Wireless using a Unite Explorer hotspot. It has been working fine for about five years now. I recently came across an application where I have to either set up UPnP or manual port forwarding. AT&T wireless supports neither. AT&T wireless will not allow incoming connections. AT&T is the only carrier available to me. The only other Internet option is satellite which will not meet the requirements of the application.

The application is a FlexRadioSystems 6500 transceiver using the newly released SmartLink. This would allow me to remote control the transceiver. The idea is I set up the radio on my network and port forward one tcp and one udp port. Then, when at Starbucks (or whatever) I can remotely log into the radio using SmartLink with SSDR.

Now for the question… Can I set up a VPN between some device on my home network (I suppose a router?) and a droplet and then port forward over that VPN? Then my transceiver would be accessible via a static IP of a droplet and through the tunnel hopefully bypassing AT&T Wireless’ restrictions.

Does this sound far fetched? Maybe there’s an easier solution for a VPN service? I’m not trying to protect all traffic, just the traffic to the transceiver.
