        HOW TO SETUP YOUR LINKSYS WIRELESS
           ROUTER SO THAT IT WILL DCC TO  mIRC

IT'S NOT AS DIFFICULT AS YOU THOUGHT IT WOULD BE

Before you do anything, please read the instructions that came with your router.  I cannot stress this enough.

We are going to start by obtaining some information that you will need, in order to configure your settings.  Get a pencil and paper and write these items down:

Computer #1 (This is the computer that your Router is connected to).                                      
1.  Router Assigned IP#_____________________                        
2.  DNS Span_____________________ to ____________________
3.  Internet IP#_____________________
4.  DCC Port #s____________________ to ____________________

Computer #2 Router Assigned IP#_____________________
Computer #3 Router Assigned IP#_____________________  

You will need to make an entry for each computer on your Network, as the Router Assigned IP# will be different for each computer.


FIND OUT WHAT YOUR ROUTER IP, AND DNS  SPAN ARE

Get on the computer your Router is connected to (this will be Computer #1).  Go to START, then RUN.  Type in CMD   and enter.  When the Dos Popup appears type in ..    ipconfig/all   and enter

You will see a list of numbers.  Look for the entry called "IP Address".  Write that number down on the Router Assigned IP# line on your list.  The number will probably look something like:  192.168.1.100

Now look for an entry called "DNS Servers".  Write down the two numbers of the  DNS Servers (example 68.13.16.25  and 68.13.16.30) , on the  DNS Span line, of your list.

If you have other computers, you will need to repeat this procedure on each computer on the Network.  The only thing that will change, are the last three digits of the Router Assigned IP#, for each computer (example 102, 103 etc)..

Note:  The Router Assigned IP#  is not the same, as the IP address that your Internet Provider has assigned to you.


FIND THE IP ADDRESS YOUR INTERNET PROVIDER HAS ASSIGNED TO YOU

Click HERE to go to a website that will tell you what the IP#, that your Internet Provider assigned to you, is.

Look for the numerical address (example)   
IP-Address:  24.164.150.219   
Write this number as the Internet IP# on your list.


SELECT YOUR DCC PORT NUMBERS

You will need to select a range of port numbers to DCC on.  Here is the information you will need in order to make this decision:

The port ranges need to be in a very high numbered range. Do not pick port numbers below 1024 (i.e.  1 to 1023), as this could cause major problems with other protocols (FTP, HTTP, SSH, SMB/CIFS, NFS, and hundreds of others). Stick to port numbers above 40000, and do not exceed 65534.  For example you could use 47000 to 47010, or 50000 to 50010.

How many Ports?  Ten Ports are sufficient unless you will be sending and receiving more than 10 DCC’s at a time. 

When you have decided what the Port numbers will be, write them down next to DCC Port #s on your list.  We now have the information we need, and can move on to actually making the changes that will enable to you DCC successfully.


SET UP PORT FORWARDING

Make sure you are working on Computer #1 .. the one  that your Router is connected to.  These changes will be made on your Router Configuration and MUST be done on the computer that your Router is connected to.

Open up a browser and type 192.168.1.1 in the address bar, and click GO.    A Password request Popup will open.  You may have not already set up a User Name and Password.  If not, type in   admin for the User Name, and leave the Password empty; then enter.  You are now at the Wireless  Configuration Setup Page

Look at the tabs across the top, and click on the tab that says APPLICATIONS & GAMING. 


Exhibit A

On the next line, click on the tab called Port Range Forward. This is where you will be adding two entries for each computer on your Network:    
     1)   DCC, which will enable DCC receive 
     2)  mIRC, which will allow identd to work, and will also enable DCC send.


Exhibit B

Port Range for the DCC line, will be the DCC Port#s on your list. 
Port Range for mIRC line will be 113  (start and end).
Protocol - Select BOTH
IP Address - This
is the Router Assigned IP# that you wrote down for each computer on your Network.  In this example, the last three digits changed for each computer.  
Enable each entry.

When you are finished click SAVE CHANGES.  Before you leave, review each line for errors and omissions.

Note:  One other thing you might check while you are in here, is the version number of your Router software.  I had one person tell me that the reason identd would not work for them, was because they had to upgrade their software to a newer version.  So if you get to the end of this and still cannot get identd to work .. you may want to consider that possibility. Call your Router Mfg. and they can help you update your software.


REQUIRED CHANGES IN mIRC

Open up mIRC and then disconnect from the server (changes should be made while disconnected).  Open up mIRC Options (Alt+O) .. Click on the Connect tab,  then the Local Info tab. 


Exhibit C

Local Host
:  Leave empty (mIRC will fill this in for you)
IP Address:  Type in the Internet IP# from your notes.
On Connect Always Get ..  Untick  both Local Host and IP Address.  Both must
be Unchecked.
Lookup Method:    Tick the  Server  option.

Click OK,  and close. 


CHANGE THE DCC PORT NUMBERS IN mIRC

You need to make mIRC match the port numbers you entered in Port Forwarding.  In this example, I assigned 50000 to 50010 in Port Forwarding.  Depending on which version of mIRC you are using, you will find the Port Numbers in  mIRC Options (Alt/O), then click on the Connect tab, and then click on the Options tab.
Click the Advanced button. Type in DCC Port#s from your list.  Check the box that says "Use Random ports".  Click OK twice  to close.


Exhibit D

Note:  If you are using an older version of mIRC, the place where you add DCC Ports is different.  Open up mIRC Options (Alt/O), then click  DCC tab, then the Options tab. 


SUDDENLY UNABLE TO DCC FOR UNEXPLAINED REASON when you coming in from a LAN or home network?

If you are coming in on a LAN, and have always been able to DCC .. and suddenly cannot  .. this
section will probably solve your problem.  If you are not coming in on a LAN, you can skip this
section.

When you are on a LAN (home network)  the router assigns alternate IP Addresses to any computer or wireless appliance that connects to it.  You can only DCC from the computer on a LAN or network, that has been assigned the IP Address that ends in .100.   You will not be able to DCC from any other computer .. ever.  Only one computer is assigned .100 and that is the ONLY computer that will DCC. 
Here is how to find out if your computer (due to a disconnect and reconnect) has been inadvertently assigned a number, like 192.168.1.101, for example.

     1) Start ->  Run  ->  Type in:  CMD  and then enter

     2)  You will be at a DOS prompt. Type in:   ipconfig/all  and then enter

           Look down the list to find "IP Address"   :   See if that number ends in .100
           If it does, skip this section and move down to #1 below,  to see if there is another
            reason you cannot DCC.
           If it ends in any number other than .100 .. you need to perform the following, to fix it:

                 a)  Turn off any computer or wireless appliance that is connecting to your router
                        (printers, etc.).  It is one of these items that has grabbed the .100 IP  Address.
                  b)  Turn off your computer
                        Unplug your modem and wait 10 secs.
                         Unplug your router and wait 10 secs
                        Plug in your modem and wait 10 secs
                        Plug in your router and wait 10 secs.
            When you turn your computer back on, you can check to make sure it has grabbed
            the .100 address back again.  If so, you should be good to go.  If not, then something
            else is grabbing that number before your computer does.  Check again to find what
            is connecting to the LAN, that you didn't get turned off.   


IBest of luck with your DCC problems.  Hope this helps.  

Sincerely,

CometBaby
