[44net] Radio Club & SDR

Folks, I am just setting up some networking for our local radio club. We intend to have some SDR receivers and remote access to our HF Station. The issue is we do not have an externally visible IP address. Our router, and old(ish) Draytek, does support a variety of VPN services. Could we use a VPN through 44.net to obtain an externally routable IP address? Is this a legitimate use of 44net? Dave G4UGM
