How to send all Internet traffic to one PC

Hey Guys and Gals, Im looking to set my computer to receive all internet traffic before it gets sent to the rest of my pc's and other devices.

You want to DDOS yourself?

When the packets come in, i want them to be directed to my PC first, to see if they are for my pc, before being sent wherever else.

If im watching Netflix, and my daughter is messing around on her phone, and my son is playing online games or what have you, I want my PC to be prioritized.

You want to setup your QoS. You can do this in your router settings.

There is not a real simple way to do this because of wireless. You are best off load third party firmware on your router if it supports it that can monitor traffic. Prioritizing traffic is only partially possible because the ISP is in control and if they drop or delay your netflix traffic what can any router possibly do about it by the time you get the data.

The only way I know to get traffic to pass through your PC without setting up multiple routers and using your PC as a firewall is to build your own man in the middle attack.

So first problem is the DHCP. You need to feed the end users devices your PC IP as the default gateway. Most consumer routers will not let you set the gateway ip to anything other than the router. So you run a DHCP server on your PC having all the other device send their traffic to your PC. You would manually set your pc to have the router as its gateway. So now all traffic comes to you but traffic coming back from the internet does not. What you do it go into the router and put static arp entries in for all the IP addresses pointing them to the mac address of your PC. This will make the traffic flow back though your pc. You will likely have to disable some firewall options on your PC because it will detect this as a attack. You will also have to get some form of capture software you like to see the data. Wireshark can capture and analyze but not do much else.
