    network neophyte and vpn over television cable network

    i'd like to use a few of 254 cable connections on a private tv cable network to
    link windows and mac computers for file sharing. i believe i need a cable modem
    at each location and might be able to use vpn. there is already an internet feed
    on the network along with television signals.

    i know now to install vpn.
    what kind of cable modems do i need?
    will vpn work in this setting?
    am i asking the right questions?

    What do you mean by "private TV cable network?" Is it completely owned and
    managed by you? Where does the TV and internet feed come from?

    yes, it is owned and maintained by us. there is a commercial tv and internet
    feed by a cable tv company. a dozen of the 254 sites each has a cable modem
    supplied by the cable tv company. the cable modem is connected to a wireless
    access point that we supply. each a/p is limited to five computers by
    mac-address filtering.

    Now, with the information you just provided, your question boils down to:

    I have a bunch of sites connected to the Internet via cable modems.
    I would like the sites to be able to share files between each other.
    How do I do that?

    The answer is dependent on the presence and type of router, the operating
    systems used on your computers, the use and type of firewall software on
    your computers, and other issues I'm sure I'm missing.

    Possible solutions are to continue to discuss it here or in other forums and
    maybe come up with a solution that works some or all of the time on some or
    all of your computers while learning how to maintain and troubleshoot it, as
    you'll be in charge. You could also discuss it with your cable company, as
    they may offer this type of service for business accounts (I'm guessing you
    have a commercial account given what you've stated). That would have the
    benefit of some level of support. A last (and in my opinion best) option,
    is to hire a network specialist to work this all out with you and your cable
    company and sign a service contract with them.

    Good luck,

    -Gary

    P.S. MAC address filtering is a very poor way to secure a network. If you
    do start using file sharing across wireless, know that MAC address filtering
    is very easily broken. You should not count on it to secure data of any
    importance.

    thanks for your generous time and effort, gary, in getting this network neophyte
    headed in the right direction. i can see this is not going to be easy. :=)

    i want to experiment at first with a setup that does not involve the existing
    cable modems and wireless routers. i think you've answered one question: do i
    need both a cable modem and a router at each site? the answer seems to be yes.

    The answer to this question depends on how close the sites are to one
    another. If they are close enough to reach a single wireless router, you
    could do everything you want with a single wireless network. This would
    also allow you to reduce your internet connection to a single cable modem.
    Of course, you'd have to evaluate if the bandwidth provided by a single
    cable modem is sufficient for your needs.

    terrain is not wireless friendly. steep hills and dense trees separate the
    sites. am i correct that both a cable modem and a router is required at each site?

    It depends on the number of computers you want to connect at each site and
    the type of service you have from your cable company.

    If you have service that provides a single IP address and you want to
    connect more than one computer, you need a router.

    If you have service that provides a single IP address and only one computer
    per modem, then technically you don't need a router. However, I wouldn't
    recommend that as a router provides a layer of protection against network
    attacks.

    If you need wireless service for any number of computers at each site, you
    need a wireless router.

    If you have business class service and you want to establish VPNs between
    the sites, you need a business class router and somebody who knows how to
    install and maintain your network.

    As you can see, the possibilities are quite varied and depend heavily on
    your requirements and resources (money, expertise, staff, ...). At this
    point my best recommendation is for you to engage directly with a company or
    person knowledgeable about networking and the services in your area. It's
    possible your cable company can help through their business services
    division, or you may want to hire an independent contractor. In any case,
    it appears that you need professional assistance; which you won't get here.

    Good luck,

    -Gary
