Gl-X750 with no public IP address

Hello I have a GL-X750 and my 4G ISP does not support public ipv4 nor ipv6. Is there a workaround to setup a server with it, that requires public ipv4?

Use which is our reverse proxy solution.

How does this solution compair in terms of privacy and security to a VPN service?

Astrorelay is a proxy and only relay your data.

For example you can set up a local wireguard/openvpn server and relay it using Astrorelay. As the data is encrypted and protected by your vpn, Astrorelay does not add any privacy and security problems.
