mmm routing question

[SirLucious]

howD all. ok heres my situation. im moving to an apt thats going to have a single internet line brought into it with the dsl/cable or watever modem. now im planning on either going for a router or a switch but heres the kicker. if i use a switch, will i have problems hosting a server as well as having multiple users in the apartment playing CSS simultaneously and possibly on that server. not concerned about bandwidth, more of an ip concern becaues doesnt a switch not distribute ip's to its connectors and if thats the case, then having multiple steams/CSS from the same ip in the same server/same game causes problems right? heres the planned setup:

modem -> router or switch -> comp1 & 2 & etc..
theres also adding a wireless router after the switch so theres another wrench for yall to monkey with.

A switch can only route traffic to certain ports, altho it needs to be told what to do, so you can never put a switch directly on an internet line, you'll need a server infront.
It should look like this:
internet->modem->server->switch->LAN

It's THE most ideal setup, routers will ALWAYS cause problems, port forwarding is done at the server (mostly it's FULLY automatic!!)
Just run all the servers etc on the server machine and you don't even have to worry about port forwarding and stuff, it will work instantly since the server machine is directly on the internet.

so ill connect the server comp to the modem, then run another line out of the back of the server comp to the hub and have our cpu's and wireless hooked into that hub correct?

[Drocona]

yes that's correct.

please note that a hub is something different than a switch, hubs broadcast on ALL ports while switches know where to send the data too, switches give you a much more stable network.
