Step 1:
Note: If you are running Windows XP, you need to turn off the built-in Windows XP firewall. You probably already did this when you setup your router, but if not, it must be done now. Perform the following steps to get to the Internet Connection Firewall dialog window.
  1. Click on the Windows "Start" Button
  2. Click on "My Network Places" (or "Control Panel" then "Network Connections")
  3. Click on "View Network connections"
  4. Right-Click on the LAN icon under "LAN or High Speed Internet"(the one that says "Enabled")
  5. Click on "Properties"
  6. Click on the "Advanced" tab
  7. You should see Figure 1 below




Step 2:
Open your web browser and type in http://192.168.1.1/. Log in to the Linksys router configuration system with your password. You will see the initial setup page as seen below. Your entries on this page may be different, but we're not going to change any of them anyway. Note this is only the top half of the setup page. Click on the Advanced tab, shown in the red box.





Step 3:
This is the Filters Page of the Advanced Setup section. Note that only the top half of the page is shown here. Click on the Forwarding tab shown in the red box.




Step 4:
This is the Forwarding page of the Advanced Setup section. Here we will setup ports for DCC. Again, I strongly recommend you set the local IP addresses of your computers manually. Otherwise port forwarding will most likely not work. I don't have a tutorial on how to manually configure LAN machines yet, but may do so if I get sufficient requests. This demonstration will set up DCC ports for two computers on a LAN. The red arrows show the places where we will make entries.




Step 4a:
  1. Enter the ports that will be forwarded for both computers. Each computer IP will use a set of port ranges. The Service Port Ranges must be different for each computer. You don't want to have overlapping ranges. The port numbers you choose can be anything between 1025 and 65536. I suggest you use something between 2000 and 8000. The number of ports you trigger depends on how many simultaneous DCC sessions you might have going at one time. If you think you could possibly have 10 DCC windows open at once, your port range will need to cover 10 ports as shown in this example.
  2. You need to enter the LAN computer IP address. This will be whatever you defined when you manually set each up. Remember the port ranges for the specific computer as you will need them later when you configure your IRC client. When finished, click on the Apply button
  3. You will get a screen telling you the operation was successful. Click on continue.




Step 4b:
After clicking on Continue you will be back at the Forwarding page with all the DCC info filled in. Now we need to go to the Port Triggering page to setup Identd. Click on the Port Triggering button circled in red.




Step 5:
This is the Port Triggering window that will popup after you click on the Port Triggering button. You need to fill in the information in the red circles.
  1. The Application name can be any thing you want. I suggest you use Identd
  2. The Trigger Port Range contains the port numbers used by IRC servers. Ports from 6660 to 7000 cover the most commonly used ports on IRC servers. I recommend using those values.
  3. The Incoming Port Range is the Identd port number. These must be 113 and 113.
  4. Once you've filled in the information, click on the Apply button shown circled in red.




Step 6:
The image below shows the Settings Successful Window that pops up after clicking on Apply. You can now click on the Continue button shown in the red circle. This will return to the Port Triggering window. Click on the "X" in the top right corner of the Port Triggering window to close it. At this point you can close your browser and you are finished configuring the router. The last thing you now need to do is configure a couple of things in your IRC program.




Step 7:
This information is specifically for mIRC. If you use a different IRC client, the process will be similar. Launch mIRC and click on File, Options to open the Options dialog window. In the Category Menu, click on Local Info under Connect. You should see the image below. You need to clear any entries in "Local Host" and "IP Address" boxes. Next, under "On connect, always get", check the "Local Host" box. The "IP Address" box will automatically be checked. Under "Lookup Method", click the "Server" button. This will force mIRC to get your real IP address, not your LAN address.




Step 8a:
Scroll through the Catagories menu and click on IdentD. Make sure the box next to Enable Identd server is checked. Where it says User ID, fill in your username. Check "Show Identd requests" and "Enable only when connecting".




Step 8b:
Scroll through the Category Menu and click on Options under DCC. You should see the image below. In the red box under DCC Ports, you will need to clear the entries in First and Last. In these boxes, enter the port numbers you entered in the Port Triggers section of the Router setup (refer back to Step 4b). Next look at the number shown in the green box that says "Max. remotely requested DCC Sends". This number should be equal to or less than the number of ports you have setup for DCC. In this case it is 10, equal to the number of ports I have setup in the DCC Ports section. That' it. Click on OK and you're ready to rock n' roll with DCC.
