Use a forwarding service on a separate public server with a private VPN connection.

Additionally, I'm not comfortable with IPSEC if there isn't an IP interface for it. @Alef recommends checking that first. GRE can wrap all your traffic. Also consider SSH tunneling, which lets you set up a tunnel using SSH and redirect data without needing port forwarding. You can define local ports to send through the SSH tunnel to your Hertz Server.
Looking forward to trying again soon after finishing my exams. Appreciate your support!
