To do that you need to do it for the nic connected to the internet, and you'd want to limit it to a bit under the total bandwidth, for 256kbit i'd recommend something around 244-250, but it varies on the isp as to how reliably you get a full 256kbit. Then how you split up the bandwidth completely depends on what you are trying to accomplish. - Jody Ricardo Chamorro wrote: > I have a connection cablemodem (down 1024kbit up 256 kbit) that > spreads Internet to a LAN of 4 PC.
