What will happen to the bandwidth on this config??

[CP]

Suppose I have a 4-port router, a 4-port switch and 6 PCs, and would like to link all the PCs together and share the Internet connection (Cable). If I connect 3 PCs (let say A, B and C) directly to the router and let one port hook up to the 4-port switch then split to the other 3 PCs (D, E and F), will the PC D, E and F get lower bandwidth if all PCs hook into Internet simultaneously?

Besides, is that possible to do "port-forwarding" for all the PCs (including those attach to the switch)?

Any help in advance will be highly appreciated.

Thanks
CP

Technically no. They should all get the same bandwidth. Even if the PC's connected to the switch do get slightly less bandwidth, you aren't going to notice. This is especially true if the router is hooked to a cable modem/ADSL, because that will be your limiting factor, not the router or the switch.

Yes. There is no difference being on a switch or directly on the router, because port forwarding happens on a higher layer (layer 3/4 I believe) of the OSI while dumb switches work on layer 2.
