Actually you could give your empeg an "Internet ip address" as well as long as it lies within th same subnet as your PC, but this is not realistic.

If you want to be able to connect to the net AND your empeg simultaneously via ethernet you could get a broadband router and configure all the devices to have ips within the same subnet..

There are lots of variations and from the sound of your question none of the answers here will really help you get it working. You'll need some amount of technical knowledge to get this stuff working. The empeg is not a very novice user friendly device, and neither is networking..
