How do I connect my computer to a router for home networking without sharing the internet?

Question

Here is my setup:
1 Desktop Connected to local Comcast Broadband Cable
(has 2 NIC cards installed)
1 Lynksys wireless router connected to Qwest DSL
3 Laptops with wireless adapters

Here is my Problem:
I want to share all computers on a home network for filesharing only. The Desktop needs a dedicated Broadband connection. and the Wireless Router will share the DSL for the laptops..

I have the Desktop Connected to the Broadband modem on one NIC and to the Router on the other NIC. How do I disable the DSL to the Desktop, from the Router, while keeping the LAN filesharing capabilities on? Alternately, How do i prevent the Desktops Broadband from being shared to the Router?

I know this sounds complicated, but if you understand this, then I assume you know as much if not more about this situation than I do and would love to hear some good answers. Thank you in advance.

Answer 1

use a switch or a 2nd router and use ip blocking to block external access from the desktop on the othe rconnection as i assume that you have 2 isp's. all the computers will have filesharing capabilities as long as they are on the same ip range or subnet mask such as the other router can have192.168.1.1 but if the subnet mask is the same then they can communicate.

Answer 2

I am not sure...but manually confitujre your IP network to use something like the 10.x.x.x addressing? Don't put in any DNS information. If you can't figure this out let me know and I will setup a test system and figure out how to do it for you.

Actually this is pretty easy.



Manually assign IP addresses to all of the devices beyond your router. Then at the router configure it to allow passthru for only the IP address(es) you want.
