Netgear RT-311


1. Access the configuration menu from your web browser (

2. Login using… User Name = admin, Password = 1234 (these are the defaults).

3. Select 'Advanced', and then 'Ports' from the main menu.

4. Under 'Port #' enter 6699*.

5. Under 'Server IP Address' enter (see note).
6. Under 'Port #' enter 6257*.

7. Under 'Server IP Address' enter (see note).



8. Click 'Apply', then 'Logout'.

9. Read Important Note.


* The port numbers 6699/6257 shown here are the default ports that WinMX uses, if you've chosen to use port numbers other than these in the WinMX Settings menu, then you'll need to reflect the changes here.



Important Note   (Top)

The IP address shown in the above examples (192.168.*.*) represents the Local Area Network IP address of the machine that operates WinMX. This IP address will need configuring.  You can find out what your local IP address is by going to… Start Menu > Run > type ‘cmd’ or ‘command’ > Then type ‘ipconfig’ in the command prompt window that opens; the results should look like the following…


Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . :
    >>> IP Address. . . . . . . . . . . . : <<<
        Subnet Mask . . . . . . . . . . . :
        Default Gateway . . . . . . . . . :


The local IP address is the internal network address used by the machines on your Local Area Network, not the external internet address that your Internet Service Provider provides.



The diagram above demonstrates both internal and external networks, each using a unique range of IP addresses.  The IP address that needs entering into the Router port forwarding rules is the Local Area Network IP address of the computer running WinMX, for example Computer 2 @, or Computer 3 @, or Computer 4 @


The external IP address ( in the above example) is automatically assigned by your Internet Service Provider.  It operates outside of your Local Area Network, and is not used in any way when configuring port forwarding rules in your Router.  The Router itself is a bridge between 2 separate computer networks, the first being the external ISP network, the second being your own internal Local Area Network.  As the diagram above shows the Router actually uses 2 IP addresses, one representing the end of the line for the ISP network, with the other being the gateway to and from your own local area network.


It's important to assign static IP addresses for your LAN computers (example,,, etc.) so that any forwarding rules you create in the Router configuration always direct the information received from the internet to the appropriate machine.  When someone attempts to download a file from you, the packet is addressed to, destination port 6699 (example); this is the address of your Router.  When the Router receives the packet it looks at it's rules to see which computer the packet should be forwarded to, so if the Router has a rule saying...


TCP 6699 forward to


...then upon receiving a packet addressed to port '6699' it will forward it to, which in the above example is Computer 2.


By default Windows configures Local Area Network computers with dynamically assigned IP addresses to use each time the computers are restarted.  This means that on one day the computer running WinMX may have the address, and the next day Windows could have assigned it  This would cause any forwarding rules that you create in the Router to fail to operate as the target machine's IP address would keep changing, so it simply wouldn't be able to forward the incoming connection to the appropriate machine.  Imagine a Post Office worker trying to deliver mail to houses that keep changing streets! :-)


For now I'll leave it up to you to figure out how to configure your machines with static IP addresses (it's not too difficult), I'll see about knocking up a page that runs through the process sometime.  Until then, Google is your best friend. ;-)
