    Where the fibre-cable enters my house, I've three boxes on the wall. First it enters a
    box, model NIU-2D4TB from Dinh-Telecom (I couldn't find much info about it, except for
    the fact that Dinh-Telecom is a Belgian company). Where there is a label "-5dB/1dB", a
    coax cable exits and goes to a Motorola SB4200E SURFboard Cable Modem
    http://broadband.motorola.com/catalog/productdetail.asp?ProductID=180). From there a
    cable goes to a "5 Port Mini-Hub" (no model or vendor visible on the box). From there, 2
    cables exit, one to PC1, the other to PC2.

    >Is [the Windows] PC1 getting an IP address from your ISP?
    Using the command "winipcfg" I get this information:
    adaptoradress: 00-03-E1-40-35-90
    IP-address: 81.83.45.35
    subnetmask: 255.255.254.0
    Standard Gateway: 81.83.44.1

    >How many leases have you purchased from your ISP?
    Have no clue... I subscribe to a service that allows me to have 2 PCs connected to the
    internet, each one with their own IP-address. For those who understand dutch, the product
    info page is: http://www.telenet.be/producten/internet/telenet_internet/duo/index.php
    ,and the installation layout is at
    http://www.telenet.be/producten/internet/installatie/installatie_duo_quattro/index.php It
    mentions that you only need a hub and no router, but no word about leases.

    >Did you purchase the cable modem?
    My ISP installed it, so I guess I lease it from them.

    So it seems that what you said (that my hub won't do Network Address Translation [NAT]
    and/or that my cable modem only allows for exactly 1 network card MAC address and
    completely IGNORES other requests) is happening.

    IF this is the case, I will likely go for option 2 you suggested (purchasing a 2nd
    Network Interface Card [NIC] (~$10-20 US) for PC2, connect the cable modem to the machine
    that has 2 network cards , connect the other card to the hub, set up NAT, install a
    Firewall, and possibly reset my cable modem.)

    Before I do this, are there any other checks that I can perform to know for certain that
    this is the case. And can somebody tell me in detail what this lease thing is. If we're
    positive, I will install the second NIC and tell how it goes,

    Thanks for the good support until now, and looking forward to the feedback,
    Jeroen

    Sorry, my fault. It is in there, but I somehow didn't copy it.
