    Hi i need some help, i have got a sar715 Router and have got 1 computer
    connected to it, and one crossover cable connected to the uplink which goes
    to another computer, which i will call my server, with 2 ethernet cards, the
    second ethernet card feeds a hub via straight through cable and from the
    hub, 3 other computers are connected, the reason for this setup is I want to
    be able to limit bandwidth to the 3 computers on the hub, i use a bandwidth
    management software, all works fine apart from one thing, my computer thats
    connected to the sar715 cannot see the other 3 computers on the hub, it can
    see the server computer, is there anyway of sorting this out? all 5
    computers are running windows xp pro.
    Thank you all for your help in advance.

    Nice1.

    Numbering the PCs in the order you mention them, you have two networks: one
    comprising the router and PCs 1-2; the second comprising PCs 2-5. Right?

    What "bandwidth management" software are you using?

    Does PC 2 perform address translation (eg using Microsoft Internet
    Connection Sharing) for PCs 3-5?

    If the answer to the last question is "yes," and the bandwidth management
    software allows suitable configuration, the simplest solution would be to
    get PC 1 on the same network as PCs 3-5, so that all Internet traffic goes
    through PC 2. An alternative solution would be to replace the router with
    one that can do the same job as the bandwidth management software, and
    attach all PCs directly (possibly via a hub).

    If PC 2 is /not/ performing address translation, then you need to set up a
    route on PC 1 to direct traffic for PCs 3-5 through PC2. But I guess this
    case doesn't apply, as you would have already needed to add a route to the
    router. Which leads to one more solution: if PC 2 is performing address
    translation, then turn it off and add the necessary routes to PC 1 and the
    router (the latter may not be possible).

  3. Difficult one! I would try setting the IP address on the single machine to
    something diferent to the other 'cluster', e.g. 192.168.1.1 /255.255.255.0
    and the cluster 192.168.0.1 through 4. / 255.255.255.0 . Hopefully the
    router should be intelligent enough to deal with this. You may have to
    configure the routing table a bit.

    This is just a guess!! Note your existing setting before trying!

    What addresses are the various boxes using?

    Hi , I have set the router to DHCP, originally DHCP was not enabled so i had
    to input all the ips into the Internet Protocol (TCP/IP) This was ok but
    still i could not see the network from PC (1) and yes Alex you are correct
    on the lay out of the PCs, PC (2) has ICS enabled and PCs 3-5 have theres
    set to obtain an IP and DNS address automaticlly and no PC 1 has the same
    settup, i did not want to put my PC (1) through PC 2 as i thought it might
    slow things down, but i am not sure as i am a noob to all this but willing
    to learn, the software i am using is Bandwidth Controller
    http://www.bandwidthcontroller.com/ it seems to do its job.

  6. This type of situation is really best handled by a Linux box, most logical
    would be to stick a PC running IP Cop or a similar specialist Linux
    between the hub and the router-modem and connect everything else to the
    hub. The IP Cop box can do the throttling with different settings for
    individual pcs and gives you a caching proxy server and gives you a bullet
    proof firewall.

    A basic IPCop set up takes about 20 minutes privided you have an old working
    486 or better PC with 2 network cards (or like use a single pci dual nic
    card), once setup it dosen't even need a keyboard or monitor.

  7. The way I see it the only pc to use the router DHCP is PC1. PC2 has ICS
    enabled and will have a static address of 192.168.0.1 and PC3,4 and 5 will
    obtain their IP from PC2. The reason you want PC3,4 and 5 to go through PC2
    is so you can control their bandwidth.

    As far as PC2 is concerned any traffic (and only traffic) not on the IP
    192.168.0. subnet is 'internet' traffic and is routed out through the NIC
    connected to the router. All other local traffic is sent out to the NIC
    connected to the hub with PC3,4 and 5. The DHCP request from 3-5 will be
    served up by PC2 and will not pass through to the router so the router will
    never be aware of these machines.

    So unless your router has a configurable NAT, AFAIC, you're stuffed!

  8. Addendum to my last reply - unless it's physically possible to connect PC1
    to the hub.

    There's no reason that connecting PC 1 through PC 2 (so that PC 2 alone is
    attached to the router) should slow things down. From the looks of it, there
    shouldn't be any problem configuring Bandwidth Controller to do whatever you
    want. So my initial recommendation stands: get all PCs on the same network
    and route everything through PC 2.

    Hi, Well first off i would like to say thank you to all your very fast
    replies again thank you.
    I can put PC 1 into the hub and it works just fine and it sees all the other
    comps on the network, but its the messing around with bandwidth controler to
    PC 1 that i am not happy about, the reason i am controling the other PCs 3-5
    is that my children use them and are for ever hogging all the bandwidth now
    all they get is 300kb between them and for me i get all of it :) when i want
    it, mostly its because i play alot of online gaming and it messes with game
    play even if they are just surfing the net. I like the idear of a Linux box
    runing an IP Cop do the throttling, what software would i need to do all
    this, and i like the idear of about 20 mins to set it up, if you would all
    like to put your pennys worth in about this set up i would be very very
    grateful.

    Thank you

    I haven't tried throtling with IP Cop as bandwidth contention isn't a
    problem for me but I use it for firewalling virus and spam filtering.
    All thats required is to download the IPCop Iso burn it to a cd and load it
    on to any old pc the specs say 486 and 32mb but I would recommend a bit
    higher spec as you intend doing a bit more than simple firwalling -- any
    case it is much easier if the PC can boot from CD Rom -- and I have never
    seen a 486 that could.
    The brand new version of IPCop 1.4 is a bit more picky about hardware than
    the earlier 1.3 which is still available.

    Set up is simple install with 2 network cards installed and connected just
    boot the PC and the installer will ask a few simple question.
    Once installed a monitor and keyboard are no longer required as all setting
    can be changed remotely via a web page.
    For how to set up throttling I would ask at http://www.ipcops.net/

    Why are your games more important than your children 'surfing the
    net'? Wouldn't it actually be easier to agree within the family how
    your internet connection can be used, then each one of you can get the
    full bandwidth if/when you need it.

  13. He pays for it - he gets to say what it's used for! I would say he's got a
    more realistic solution as all get to do what they want, when they want.

  14. I was quite interested in your idea and so had a look at the IP Cop web
    site. It's a firewall program and doesn't seem to have bandwidth control. I
    did try to install it, to see what I could find, but it's willingness to
    destroy all data on the existing hard drive made it a no no, as I don't have
    a spare hd atm.

    So does it have bandwidth control?

    Thank you Graham Watson for your support there, Chris Green its not that my
    games are more important , and dont forget i got children who also play
    online games, so if i am surfing the net it will mess with there gaming, and
    please do tell me how i can agree within the family on using the internet
    when they are in and out of the house like two way traffic? the family is 5,
    2 adults 3 children and 5 computers, so like Graham Watson said and i
    quote>>> He pays for it - he gets to say what it's used for! I would say
    he's got a more realistic solution as all get to do what they want, when
    they want.

    The Linux kernel does the traffic shaping.

    IPCop seems very good but i have just noticed on there web site and it says:with network file shares, email etc. take a look at these alternatives, any
    thoughts on this?

    Thanx
