Setting Up Subsonic on VPN (PIA: Private Internet Access)

Hey guys! Hopefully one of you can help me. I recently installed PIA: https://www.privateinternetaccess.com/ and it broke my Subsonic server, which from my very rudimentary knowledge of VPN and Subsonic servers, is because Subsonic needs a static IP, but VPN is constantly changing it. My ports are forwarded and have been using Subsonic for years without VPN, but this time in which we live is calling to be more secure. Is there a work-around to get Subsonic back up and running?
