By syberdeath ·
I am setting up a home network and have the following hardware.

1 Linksys 5port swtich/router w/uplink and wan port
1 D-link 5port managed hub w/uplink
cable modem
4 computers

here is what i want to do.
i want to have one of the computers outside of the router with full access to the net and the other three behind the router. how would i connect the hardware to allow me to do this? Thanks in advance.

What you are asking is not practicle. What you can do is setup the 4 PCs with static IP addresses and disable DHCP on the router. You set on of the PCs to be a DMZ host in the router configuration and this bypasses the firewall. Be sure to use an IPaddress in the same scope of the router, ie 192.168.1.?
The Linksys manual will show you how to set up a DMZ host. Plug all of the PCs into the switchports on the hub and the cable modem into the WAN port and it will work, you won't even need the hub unless you plan to expand later.

i have tried that setup and the router still blocks some, i have tried every concievable setting for the router to allow me to access the net unrestricted but it still holds back some. i have tried port routing and stuff like that and then theother pc's cant access the routed ports

You need two IP address from the ISP.
Your cable modem must have at least two ethernet ports, one for your PC the other for you router, the hub would connect to the router ethernet port.

What do you mean by having one computer "outside the router"? DO you mean that the router is a firewall or what? What it would look like to me is that you need to set up a proxy server to act as a gateway to the net.

The proxy should have dual nics, one to go out to your cable modem for the net, and one to go to the rest of your network. Your proxy server can act as your network computer that would host your web server as well as provide net services to all the computers connected behind it.

This approach will solve several problems for you, the first is that it will solve the problems of multiple IPs and technology conflicts. For the purposes of the ISP, your network will only have one computer because that is all that the outside net will see.

Are you familiar with how a proxy network works? If not, email me at wfrazee@hotmail.com and I can help you more. At any rate, when you have a cable modem and multiple PCs it is easier to set up the network this way even though it might mean more complex networking for your other computers.

To clarify a little bit, your proxy machine should have two NIC cards. The first should be connected to your cable modem which then connects to the net via coaxial cabling.

This proxy server is your one computer "outside the router". If you added a firewall program such as black ice defender server, you could run the proxy as a firewall in addition to being your web server.

The other NIC card connection goes to your hub/switch. Each of the other computers/peripherals plugs into your hub.
If proxy server software is on the computer, or it is NT or W2K server and proxy services are enabled, the second NIC card will provide net services to the rest of the network.
