Router and Servers

Posted on 2006-04-28

I have a DrayTek Vigor2600 plus adsl router. I know how to use Open port settings to direct traffic to an internal server. This has worked fine so far but now i need to do more. My ISP has given me a range of IP address. I was wondering how do i use them?

If i have available to me a set up IP addresses on subnet how do I get them to be directed to an internal server?

The range of IP addresses is not the same IP address as the one I use when surfing the net.

    have you tried to specify each network card to use a different static ip address and set the address manually?

    Can the DrayTek support mutliple "public" IP addreses.  I found one referecne that shows this boxes setup page with a "NAT" option.  You may want to look there.

    The DrayTek box needs to support multiple public IP address.  Then it needs to be configured to NAT the public IP addresses to the private IP addresses that your computers use on your network.  Each computer you want to NAT should have a static IP address within you private IP address range.

    How would i be able to tell if my DrayTek router can support multiple public IP address. It's the Vigor2600 plus adsl router.

    I look at their web site and they say the box can do "multi NAT".  I assume that this means it can support multiple public to multiple private NAT'ing.

    Does the setup page have a NAT link under the Advanced options?  Click on that and see what menu it brings up and what options are on that Menu.

    Your 2600G is able to support Multiple Public IP Addresses in one of two ways.  Either through NAT or through; If I recall correctly in the DynDNS tab.  I would stick with NAT.  Network Address Translation (NAT) would take the public IP Address and route it over to any private IP. LIke giltjr mentioned your servers or computers must have static ip's.

    Public ----- using NAT -----> Private DNS Server
    Public ----- using NAT -----> Private Web Server
    Public ---- using NAT ------> Private File Server (FTP) or something...
    and so on.....

    Once you do this make sure you go into your UPnP or Forwarding Tab and select the services ports you need traffic to:

    DNS UDP 53/53  ------> goes to
    HTTP TCP 80/80 -----> goes to
    FTP TCP 21/21 ------> goes to
    and so on....

    Hope this helps..
