Ethernet packet sniffer/Injector?

I'd like to make a device which can act as a single Ethernet hub as follows bellow

Internet->mbed->Laptop

and

Internet<-mbed<-Laptop

I'd like the mbed to transfer packets back n fourth while being able to output each packet through the serial monitor.

I'd also like to Inject packets at will through serial which the mbed will send either way to the internet or to the laptop.

Is this possible and what hurdles would have to be taken into consideration?

Basically I want to make this as a personal project which will I will be able to connect to a server and upload a custom packet on a button press on the mbed or custom packet through serial to the mbed which will be sent to the server.

Please lets make this a reality I see many prospects coming from this.
