## Issue Description

### What's the version are you using

free5GC v3.3.0 (latest stable version) on Ubuntu Server 20.04.6 with BASH 5.0.17

### Is your feature request related to a problem? Please describe.
It isn't a problem exactly, however it would be better to have [those configurations](https://free5gc.org/guide/5-install-ueransim/?h=reboot#7-testing-ueransim-against-free5gc) mentioned on the installation section of the documentation applied easily.

### Describe the solution you'd like

To have a nice and easy solution, I'd suggest coding a script to execute the commands faster.

### Describe alternatives/workarounds you've considered
It might be possible to use other iptables and/or kernel configuration files to make those configurations permanent on the host, but for now I'd suggest the script as an easy method of solving the issue.

Maybe in the future I/we could change the installation instructions with those permanent instructions (I didn't do it already as I couldn't test it myself yet).

### Additional context

I already made a PR to the repo with the suggested script.
