Bandwidth Management for my Neighbours with a Zyxel

    I am considering buying a Zyxel 662HW or 650HW, the Bandwidth Manager
    (BWM) interests me.

    I will be ADSL enabled in a few weeks time, the location is a long way
    and there are very few good wires in my location, probably I have one of
    very few homes in the area that could get ADSL as almost everybody is on

    I am guessing at best I'll get 512kb/s ADSL, but would consider using a
    wireless router to allow my neighbours having some internet access.

    So, can I use the BWM part of the Zyxel routers to provide them, over
    WLAN, a maximum bandwidth of say 128kb/s? Id still like the remainder of
    the BW available to my wired iMac and my Laptop over WLAN.

    Not sure, but after downloading and reading the Zyxel manuals, I think
    if I staticaly assign my neighbours an IP address (I will know their
    MAC) to a subnet, say and keep all my own devices on, then I can use BWM to reserve 128kb/s for the neighbours
    .... anyone care to state if I have this correct?

    Very neighbourly, but probably a breach of your "Terms and Conditions".
    Tread carefully!

    And don't forget that anyone using your wireless potentially has access to
    all you machines. If you did do this, you might consider placing another
    NAT/firewall between your PCs and the WAP/ADSL modem to protect you from
    everyone else. And make sure your neighbours realise that they would all be
    able to "snoop" each other's computers unless they also installed firewalls.

    A firewall WILL NOT HELP, well, not much. Maybe it'll deny access to Windows
    shares, but it wont stop people from sniffing the traffic for plain text
    passwords, like POP3 accounts etc. If you trust your neighbours, then you're
    sorted, if not, then you better make sure you know far more about computer
    security than any of them because if John at number 7 breaks into everyone's
    POP accounts, guess who'll be blamed!

    And as far as terms and conditions go, well, they don't enforce that you
    enable WEP, and your neighbours just automatically connected to the nearest
    AP, you knew nothing about it.
    "I wondered why my net connection was slow" ;o)

    Although it is possible for your ISP to map your network, even when using
    NAT, I doubt they ever would, and if they do, kick up a huge fuss about it!
    Plus, it's fine to run a home network, so they'd never know.

    Good luck though, if only the world had more people willing to share like

    Take most of your points but if you're allowing passwords out "in the plain"
    then you deserve all you get. Any reasonable ISP should have secured access
    (i.e. password not in plain).

    In addition, your router will almost certainly be a switch so you won't be
    able to Sniff any more that you could with any other "switched" network.

    Of course all the neighbours will know the initial WPA-PSK (or WEP) pass
    phrase which would aid any "direct" WAP Snooping but as to just "seeing"
    information in plain text, I'd be surprised.

    As far as I'm aware, most ISP's still use plain text POP3 logins. At least
    by default... and certainly most users wont look for more secure options
    because they aren't aware of the security implications.

    Also, and again, as far as I'm aware, you can't "switch" wifi because of the
    nature of radio. (nearly) Any card can be put in slapper mode and sniff all
    the packets sent over the network.

    Having said that, it is actually possible to sniff switched networks.

    Of course, all this is probably pie in the sky since most users (neighbours)
    will just read there email and chat on MSN. However, you always get the odd
    one (or the odd one's son) that wants to make your life a misery and spoils
    it for everybody else. Shame.

    Again by placing them on a subnet, I can use the firewall rules to
    block access from 'them' to 'me'.
