How to use an old laptop as a "server"

Dec 6, 2017 5:38AM PST


I want to use some software to block adults websites and other stuff on my home internet.

I'm planning to buy a usb 3.0 to rj45 and connect the usb to the laptop and the rj45 to the modem.
after that, I want to connect the laptop to a router so every computer in my house could connect to my router with a safe internet.

The problem is - I do not know how to make my old laptop using the rj45 as an output and not as an input (because I want it to transmit the data from the modem to the router.

I know it is not a server but I want it to work in the same way - so how can I do that?

Luckily for you, Ethernet is bidirectional. If you type a link, the rj45-port is output. If you receive an answer (a webpage) it's input. So - whatever other problems you might encounter, and I'm afraid it will be an unsurmountable lot - not an rj45 port doesn't do output.

incoming from ISP goes to the modem, then from modem to the router, then from router to LAN, either wired access or wireless. The router protects your internal IP address by NAT. You can also set up the firewall in it. It's what will supply wireless to any wifi connected devices. It's what helps protects your private computer from directed attacks through the internet.

As for blocking porno sites, there are softwares available like Net Nanny.
