    Switch / Router

    My father in law has two PC's and a cable modem. He wants to share the internet and printer. Im thinking about just using a switch. So from the cable modem to the uplink on the switch, then out to the two computers. Any problems with this configuration or should I just get a router?
    Thanks John

    I'd recommend getting a router. Most home routers have a basic firewall which is a good first line of defense in additon to a software firewall on each PC. See Home and Small Office Networking with Windows XP for information on getting the network going.

    Thanks Joe,
    You're probably right. I am not sure what he has in regards to a firewall or anti virus.
    But I could use just a switch couldn't I if I were to also install something along the lines of ZA Pro? or NAV w: firewall?
    Thanks John

    The router is still better, but one still needs to run a good s/w firewall to control the OUT going.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    I agree with Dave. Spend the money on a router. They are pretty inexpensive. Unless he really wants to get into configuration and fine control use a free firewall on each PC. Same with A/V - use a free one.

    You need some way to get the single IP address that the Internet company assigns to your line translated into multiple different IP addresses for each PC that you want to share that line. A rouer like this one http://www.mwave.com/mwave/viewspec....iteria=1043563 does this by automatically assigning private IP addresses to your home computers (called DHCP) and trasnlating them to the internet when necessary (called NAT). This box also acts as a 10/100/wireless switch, so you can plug evertything into that unit. It also has firewall capabilites, and other useful features for gaming and application access. For $60, I don't think you can go wrong.

    On the other hand, some cable/dsl modems have the IP addressing and firewall stuff built in, so they are basically routers themselves. You might want to check into what he has first and see what it can do.

    I guess the operative question is... why do you feel the need to use a switch? The purpose of a switch is to glue together different Ethernet segments on an internal network and provide a speed increase.

    A router suits your needs more directly, as it is designed to sit in between the WAN (external) and LAN (internal), and will provide address translation and multiple IP addresses to boot.

    John,

    if you only want to use a switch in this matter (a router would be more advisable) then you can only get a connection on pc at the time. Only one IP address is given to you and only one pc can use it.

    If you buy one or two NICs extra to be fitted in the two pc's ( one with two NICs and one with one) the pc with the two NICs could provide access to the net simultaneously; BUT all previous configurations are way much better and safer for this matter.
    Go for the router/switch an you will have the best of it for the time to come. I am running the same configuration an a small network of 4 PC's and it works fine.

    Re: Switch / Router

    I strongly recommend you use one of the following:

    D-Link DI-704P NAT Router w/4 Port Switch + Print Server for $60.54
    or
    D-Link DI-704UP NAT Router w/4 Port Switch + USB Print Server for $60.79

    I have installed several (a dozen or so) of these. They are identical except the second has a USB print server, the first uses the traditional bi-directional LPT port.

    The great thing about using one of these is the printer hangs off the router and not a PC. Therefore, file and print sharing does not have to be opened exposing you to other vulnerabilities. No PC has to be turned on and connected for the other PCs to print - or access the Internet. And what I really like is the printer can then be located in a central location and not tethered to a particular desk. Even All-In-One multifunction printers work fine.

    Very easy to set up - and the price is right too, considering a stand-alone D-Link Print Server costs $60 by itself.

    Wireless versions of all the above are available too, but of course cost more, and then being wireless, they of course open up a whole new set up security concerns and responsibilities. Note too that D-Link has an established reputation for making reliable networking devices - and no, I am not affiliated with or own any D-Link stock! <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    MWave also carries both models at comparable prices, but ZipZoomFly offers free shipping. I use both vendors (as well as Newegg and Monarch Computers) frequently.
