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

Close to the top of the lphant window there should be a row of buttons. Click this Options button in this row.

You should see a TCP Port box and an UDP Port 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.
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 172.19.3.1.
You should see a box prompting you for your username and password. Enter your username and password now.
By default both the username and password are admin. Click the Ok button to log in to your router.
Please visit our Default Router Passwords page if the username and password shown above do not work for you.
Click the Configuration link near the left of the page.
You should now see a new menu. In this new menu, click Security.
Click the Advanced NAT Configuration link near the bottom of the page.
Click the Add Reserved Mapping link near the bottom of the page.
We will list a series of lines here that will show you exactly how to forward the ports you need to forward. lphant requires you to forward the ports you entered above. Go ahead and enter the settings shown above into the Add Reserved Mapping menu and then click Add Reserved Mapping.
| IP Addresses | Transport | External Port Range | Internal Port Range | |||
| Global | Internal | Type | Start | End | Start | End |
You should see another page of settings that need to be entered into one of the blank lines on your routers Add Reserved Mapping page. Go ahead and enter those settings and then click Add Reserved Mapping.
| IP Addresses | Transport | External Port Range | Internal Port Range | |||
| Global | Internal | Type | Start | End | Start | End |
Click the Save config link near the left of the page.
When you're finished, click Save near the center 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.
