Configuring multiple Static IP address in Speedtouch 546 v6

    Hi All,
    I've broadband connection, Speedtouch 546 v6 router and i'm running
    various servers (Web, e-mail etc) on Windows 2003+IIS 6.0

    I've 8 static IP addresses provided by ISP which I wish to use so that
    I can assign websites on different static IP Addresses.

    Can anyone help me in setting up router for multiple static IP
    Addresses? IT may not be speedtouch specific but can be general method
    to set up multiple static IP Address.

    At present I use NAT with single Static IP address and all servers
    have same public static IP address.

    I've been doing search on this and came to conclusion that
    1) I need to get rid of NAT (Is this true)
    2) Setup Static IP/Mask in router the way it is setup for Ethernet
    3) Assign these Static IP addresses to the Server
    - This one seems to be tricky. Do I need to create multiple IP
    Addresses on Server or Point all Static IP addresses to single IP
    address on Server?
    Since NAT has to be disabled then it seems that I can't use local IP
    addresses and point static IPs to them?

  3. All you need to do is turn off NAT and assign the fixed IP addresses to
    the servers with netmasks of and you don't need to specify
    a gateway.

    If you want to LAN the hosts for inter-host traffic to remain inside your
    property then that will cost you 3 IP addresses including one for the
    router/gateway. Then give the server hosts netmasks of
    and give the address of the LAN side of the router as the WAN gateway.

    Thanks Tony.
    I'll try and see if I can figure it out.

    When I turn off NAT the static IP Address goes to Router login page
    from client.

    So if I turn off and type the static IP address in web browser from a
    client PC on Internet then the Router login page is displayed.

    How to avoid this?

  5. I'm not clear what you mean by "the static IP Address goes to".

    If you connect a computer workstation to the router, do not use DHCP but
    configure the workstation's network adapter interface IP address to one of
    the static addresses give by your ISP.

    "the static IP Address goes to" refers to typing any website's URL
    which is hosted on server and which ends up in going to Router login
    page. This happens always whenever I disable NAT.

    Send part of answer seems to clearing out cloud. I'll give it a try
    and let you know.

    Well, here's how my no-nat multi-public-IP address setup is configured:

    You have 8 IP addresses.
    This means the subnet mask for your LAN is

    Let's say for example they are: thru
    The lowest and highest ( .64 and.71 ) are reserved, you cannot use them.
    The first useable address ( .65 ) will normally be your router.

    -> Configure the router LAN side as /
    -> Leave the router WAN side to 'obtain automatically'.
    -> Turn NAT off.

    Now, assign IP addresses to your PCs as you see fit, you have addresses .66
    thru .70 to use.
    Yes, of your 8 addresses, you only have 5 useable for machines.

    -> PC1 : IP =, Mask, Def. GW = IP of router
    ( in this example. )

    etc, etc.

    That's all there is to it.


    Of these, 2 are reserver ( the lowest and highest );

  8. Sorry. When you configure the IP address of the network interface adapter
    of your workstations, do not use "Obtain IP address automatically" but set
    its address to one of your assigned 8.

    If 6 are enough for servers, it may be simpler to LAN those addresses and
    then you can assign one of those 8 to the router and use that to configure
    and view the screens of the router.

  9. As I tried to explain, that approach costs 3 addresses in overhead for
    network address, broadcast address and the router). A LAN approach is
    great only so long as Nirvana only needs to use 5 of his 8 public
    addresses for host servers, workstations etc.

    5 is better than 1 as long as I make it work.
    I don't have much in LAN I just need one Laptop to hook some times.

    On a Draytek 2600 this is known as Multi-NAT

    Check your Speedtouch manual for something similar.

    I've been working out on the same but can't figure out my static IP

    ISP has assigned me
    What would be my starting static IP Address? 240 or 241.

    The static IP Address I'm using now is 241.

    Here is what I did:
    1) It seems that the starting IP Address is x.x.x.241, so I assigned
    242 to LAN Mask
    DHCP Off
    NAT disabled

    2) Configured the Server with additional static IP Address to use Mask
    I also have the old IP addresses configured on my Server (

    3) To test I pointed one of my website to use and
    waiting for domain to be resolved.

    So at this point of time I'm still on old configuration and also using
    new configuration in no-nat-multi-static-ip configuration. I can tell
    result only after 12-24 hrs

    Am I doing any thing wrong?

    I know I'm making it complex, but I just can't throw out old
    configuration and switch to new one.

  14. You have been give 8 addresses from .240 through .247 inclusive and you
    can either use them all for 8 hosts or you can LAN them and use just .241
    through .246. Then address .240 is lost as the network address and .247
    as the broadcast address (for ARP) and you would also need to assign one
    to the router as the LAN gateway to WAN. The netmask is

  15. I don't understand what you mean by "I pointed".
    What should take more than a few milliseconds? You are not waiting for
    DNS as you are using numerical addresses. It should work immediately when
    configured correctly.

    For the server on .243, what was configured as its gateway address? If
    you are LANing the addresses you need to set the gateway addresses of all
    the LAN hosts to the LAN address of your router. What is the LAN address
    of your Speedtouch?
    Not enough information yet.

    Try this:

    Speedtouch: set LAN interface to:
    IP Address: x.x.x.241

    Server: set interface to:
    IP Address: .242 (or any other value from .242 through .246)
    Gateway: x.x.x.241

    I think I'm getting closer to it now ;)

    All I need is to run webmail server on a different IP Address, than
    what i'm using with IIS, and use port 80. I've configured Win2k3 box
    to have multiple IP address,

    I'll bind all IIS websites to use and webmail server to

    I might need to disable socket pooling

    All seems to work in theory, i'll give it a try in evening and update

    Here are my settings now

    Speedtouch: LAN interface
    IP Address: x.x.x.242

    IP Address: x.x.x.243
    Gateway: x.x.x.242

    DHCP Off
    Nat disabled
    There is only one IP configured in Server i.e. x.x.x.243

    I've changed A record of to use x.x.x.243

    I can access from my Server (LAN)
    I can't access from a client PC on Internet

    What does it mean? Have I got LAN side setup correct but something is
    missing in Router side?]
    Nirvana, Aug 8, 2007
  19. That looks very similar to my current setup except I use a Netgear router,
    my IP allocation is /27 so my mask is and my ISP is AAISP.

    What is the WAN IP address of the router? The routing of my /27 is sent
    via a separate single IP WAN address (/32 netmask Is
    that how your ISP does this?

    Just as a test, try configuring your server without the LAN configuration:

    IP Address: x.x.x.243
    Gateway: x.x.x.243

    And see whether that allows it to appear to the client PC on the Internet.

    I'm with Entanet via UKFSN

    "What is the WAN IP address of the router?"
    That is a very good question :)
    How to find out what is the WAN IP address of my router?

    "Just as a test, try configuring your server without the LAN
    IP Address: x.x.x.243
    Gateway: x.x.x.243"

    I would give it a try in evening and i'll update.
