    Win XP ICS (Internet Connection Sharing)

    In my flat at university there are 2 restrictions on the network connection;

    1.) only registered MAC addresses can connect (& only 2 registrations per student)

    2.) 802.1x authentication is required on all connections

    Now because I have more than 2 machines I want to connect, & not all of them are capablle of 802.1x authentication, I have just put together an XP machine with 2x NICs, & am using it as a gateway using ICS (Internet Connection Sharing). Now the ICS works, & machines with neither registered MACs nor authentication can access the network (I am posting this from one of them), however...

    The Internet connection on the XP machine itself is fast - an internet speed test clocked a 1MB download at 3.3MBits/sec. However any machines behind the gateway are dreadfully slow. I have 1x Win 2k machine & 2x SuSE Linux machines - the Win 2k machine is usable, however slower than dial-up speeds. The Linux machines are virtually useless, often taking upwards of 10 minutes to load Google, or simply failing to load at all.

    There is nothing wrong with the network itself - I threw some video files around last night to check speeds, & got speeds above 4MBytes/sec.

    So as there is nothing wrong with the network itself, & the fact that this Win 2k machine performs better than the Linux machines, I have to put the problem down to XP. Does anybody know what might be wrong? Could it simply be that the XP machine is running with only 160MB of RAM? (Though it's own Internet connection is fast...).

    Will WinProxy handle 802.1x authentication on the 1st NIC though? Because if not, it's useless to me.

    I can't use a Linux box as the gateway because 802.1x authentication in Linux is only just emerging & is a nightmare to setup.

    I'm installing Win 2k now, & am going to try this WinProxy thing (about my last post - I thought that WinProxy was a standalone OS rather than a Windows program, where Windows will handle the authentication).

    Right it's all working seamlessly with 2k now, I'm clocking multiple Mbits/sec on all machines.

    what kind of uni forces 802.1x on their students.

    do what all students love to do, start a soc and protest, its a good way too make new friends, and like all good communitist organisations, all the founders meatings held at pubs at your members expense

    I'd be quite tempted to try and find a windows embedded system that could be used, less power consumption!

    just use a router that supports mac address cloning and 802.1 auth an old cisco router should be fine and can be picked up of eaby all nice and cheapish

    802.1x makes that rather trickey!

    otherwise what would be a very simple m0n0wall box would be my suggestion

    A friend of mine is network Sysadmin at an Oxford college. She spend half her life finding and shutting down unauthorised network connections.

    firstly those rules about what you can connect are there for a reason, partly to make the Sysadmin's life easier, and partly to protect the network and other users. Your Windows box should have been updated and virus checked for example, and if you connect other hardware you are endangering the network. If you share your connection, especially via wireless there is also a much greater risk that an unauthorised (and hard to trace) hacker may get onto the university's high speed network and cause havoc.

    Secondly, you will get found out eventually. I won't mention the tricks that your sysadmin has up their sleeve, but I am fairly sure that if you connect anything more advanced than a network printer to a shared network, it's packet signature will leak out and get traced eventually. If I where you I would cut down to one windows and one linux box, and be done with it.
