Before we can open ports for LDC++, we need to figure out what ports LDC++ is using. Here is a brief walkthrough on how to do that. Go ahead and open up LDC++.

In the menu at the top of your screen click the File option. In the list the drops down click the Settings link.

There should be a list of options on the left hand side of the window that poped up. Click the Connection Settings option in this list. Put a dot into the Firewall with Manual Port opening radio button. You should see a TCP box and an UDP box. Enter a random port into each of these boxes. It doesn't matter what ports you choose, but a port numbers between 10000 and 60000 would be a good idea. A higher numbered port is generally the best to use, because most ISP's do not block the higher numbered ports. Please enter the port you chose for the TCP box into the box below.

To configure this router's firewall you need to setup a static IP address on your computer. Take a look at our Static IP Address guide to setup a static ip address. When you are finished setting up a static ip address, please come back to this page and enter the ip address you setup in the Static IP Address box below.

Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.0.1.

You should see a box prompting you for your username and password. Enter your username and password now. By default the username is admin, and the password is password. Click the Ok button to log in to your router.
