RUT241 - Firewall setting V07.06

Hello, I’m a new user of these routers. I have no experience with firewall settings.
I would like to set the firewall so that only the router and the device with 192.168.2.2 can reach Internet servers via mobile communications. Other devices on the LAN should not use mobile communications. Access from the Internet is not required.
The router has the IP address 192.168.2.1.
A device on the LAN has the IP address 192.168.2.2.
