Automatic creat service and listen on 8443/8080/1080 ports without any authorization, right after installation

It is very dangerous to do this.

Installation will create /etc/systemd/system/multi-user.target.wants/glider@glider.service. and /etc/glider/glider.conf Automaticly.

/etc/glider/glider.conf will make glider listen on 8443,8080,1080 these three ports and accept connections without any authentication, that turns your server to a free proxy which anyone can use.

I found this out after I got traffic warning from prometheus, and my servers has become free proxy for almost 6 days. Hundreds of gigabytes of traffic are being used.

Glider is a cool project indeed, but ust really don't understand why it can be used as default setting.

And you didn't mention that on readme.
