Hardening Gained Access

Run the following in the SSH terminal to prevent your Gateway loosing root access unexpectedly.

Pick only what you need

You can paste each block directly into the terminal independently, use only ones your firmware needs. If you don't know, just paste them all. If you get any error messages from a command, just ignore it, it means that command wasn't needed for your firmware version.
