Open a port for a certain program

Hey my name is mike. i downloaded limewire on my new laptop, but it won't connect to the internet and it says there is a firewall blocking it the connection. it is deffinetely not a firewall installed on my computer because i turned both of mine off and limewire was still blocked. i was just wondering if you have a solution as to how i can stop the firewall and if the router is involved with the problem or not. if it is, should i be opening a port for limewire, and how the heck would i do that? thanks.

Re: open a port for a certain program

Hi mike,

this router has its own firewall, although i don't think its a good idea to turn off the firewall

google the port that limewire uses and then use portforwarding on the router.

you can start by turning off the firewall on the router to see if it works. if it does then perrhaps just allow limewire to passthrough your firewall at the router.

good luck

Firewall ports not open

Programs may require ports to be manually opened so that the programs work correctly when ICF is in use either on the local computer or on the gateway computer. You may have to manually open a port if there is a service that is running on a computer that has ICF enabled that you want to make available to users on the Internet.

Note The actual port settings vary from program to program.

To manually open a port, follow these steps:
  1. Click Start, and then click My Network Places.
  2. Under Network Tasks, click View Network Connections. (Or, right-click My Network Places on the desktop, and then click Properties.)
  3. Right-click the connection that you use for the Internet, and then click Properties.
  4. Click the Advanced tab, and then click Settings.

    Note If the Settings button is unavailable, ICF is not enabled on this connection, and you do not have to open any ports (because they are all already open).
  5. Click Add to open a new port.
  6. In the Description box, type a friendly name. For example, type File Sharing : Port 445.
  7. In the Name or IP address of the computer hosting this service on your network box, type

    Note You can specify the IP address of an internal computer. But you typically will use
  8. In the External port and Internal port boxes, type the port number. Generally, this number is the same.
  9. Click either TCP or UDP, and then click OK.
  10. Repeat steps 1 through 9 for each port that you want to open.
Thanks Good luck

Seems like since i purchased this router i have trouble with limewire

Have you enabled UPNP on your computer AND the router as that is one way to get limewire to work.

Also check which ports your program wants and open them up on your router

Linksys WRT160N V3 Firewall issues

You need to check first if it is the program that is causing this or not. If you have a computer without the program, have it connected to the router. If it connects it may be the program. Check if switching cable may help. IT may be a faulty cable. It may also be something in your PC that is causing this one.

Connecting Laptop wireless and Desktop wired to the router

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:

Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.

On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)

Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.

Do this on each PC and Laptop.

That should be it or darned near close.

Firewall and limewire

Dear ckclee,
Just uninstall your new limewire and restart your computer. try to re-install the old version of your "work-fine-Limewire". If it doesn't work, the only way is go to start menu, browse the accessories, carefully choose "SYSTEM RESTORE". when it runnng.. pick the date which your computer work best, the restart it, remember... windows can only restore and set back time status not more than a week, according to my experience.
Good Luck

Trying to connect between cable pc xp edition and new dell vista laptop

the SSID is only the name which your connection is called.
If you have security enabled, you will need to type in the passkey when asked.

First go to internet explorer open it and go to tools>connections tab, then tick 'never dial a connection' and close I. Explorer.

go to control panel>network connections>right click on your wireless connection icon, then go to the TCP/IP line, highlight it, click properties, then select 'Obtain IP address automatically.

Select Ok, then close window, go to internet explorer, then open it up and you may need to click refresh a few times ,but should connect

Limewire connection

you need to find your router address from your manual (eg. Then type this number in Internet Explorer address bar. If you did all ok at this point you should be opening browser control panel in Internet Explorer. Go to firewall page. Set Limewire software (you may need to use full path eg. C:\program files\limewire\) as an exception in ur firewall.
