Port Forwarding LDC++ on the Allied Telesyn AR240E

What is Port Forwarding?

View all Router Screenshots.

Before we can forward 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 Forwarding 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.

Please enter the port you chose for the UDP box into the box below.

To setup port forwarding on this router your computer needs to have a static ip address.
Try our free PF Setup Static IP Address Program which will setup a static ip address for your computer.

Or you can 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.

Do not skip this step!

Open a web browser like Internet Explorer or Firefox. Enter the internal IP address of your router in the address bar of your browser. If you do not know your routers internal IP address please read our How To Find Your Routers IP Address guide.

In the picture above the address bar has http://www.google.com in it. Just replace all of that with the internal IP address of your router. By default the IP address should be set to 192.168.1.1:8080.

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

Please visit our Default Router Passwords page if the username and password shown above did not work for you.

Click the Security link near the left of the page.

Click the NAT link.

If NAT is not enabled, you do not have to do port forwarding. Your router is setup as a bridge. You get your IP addresses directly from your ISP. If the software you are trying to run does not work, your ISP may be blocking those ports. You should make sure those ports are allowed through any firewall you may have on your computer.

If NAT is enabled, you should see a Add Reserved Mapping button on this page. Go ahead and click that button now.

We will list a series of lines here that will show you exactly how to forward the ports you need to forward. LDC++ requires you to forward the ports you entered above. Go ahead and enter the settings shown above into the Reserved Mapping Configuration menu and then click Apply.

You should see another page of settings that need to be entered into one of the blank lines on your routers Reserved Mapping Configuration page. Go ahead and enter those settings and then click Apply.

When you're finished, click Save Configuration near the left of the screen to save your changes.

And that's it! You're done!

To test if your port has been properly forwarded, you can use our Port Checker tool.
