    Are you using a router? if so, what brand and model.

  • John McGrath May 11, 2010

    What operating system are you using? Also, are you using a firewall software (ZoneAlarm, McAfee, etc.)?

Log onto your router.

Look for the NAT area, and then forward port 6880 to the IP of your computer on the same port. Torrents should get a proper connection after doing this.

Best to set the router to always give the same IP to your computer... which is referred to as a DHCP reservation. That will be somewhere on your router too, and all you'll need is the MAC address of your computers network card. (ipconfig /all in a DOS prompt will give you that information)

    Ah well, thanks for the feedback!



    If you have AV/Firewall software, you'll need to go into it's "exceptions" area and add utorrent (or whatever) as a program, and allow it inbound and outbound access. I'd recommend all ports TCP/UDP as some trackers use weird port numbers for scraping.

    Actually... your "modem" is probably ADSL or something, right? In which case, my first solution could still be valid in your case.



    The modem probably gets the WAN IP (public) and your PC probably has a private IP, right? (192.x or 10.x probably)



    If so, it is doing NAT. And if you are using uTorrent, you can go into the options for port setups, and "test" your inbound port. uTorrent will then open a webpage and show whether you are connectable via the port you have specified.

If the games are in fact, "yours" then you can configure your game server to publish on the normal HTTP port (80). Then, you will have no trouble at all.

Speedup uTorrent client with Norton and McAfee Firewall Tweaking


Make sure that the following are set in your NIS to ensure that peers can connect to you and prevent intrusion prevention warnings.

Make sure uTorrent is added to the NIS firewall and contains these two rules:
  1. Inbound Rule to permit TCP and UDP connections from any computer
  2. Outbound Rule to permit TCP and UDP connections to any computer
You must also make sure that you deselect the following in the Advanced Security Settings this is required even if the port forward test gives a positive result.
  1. Stealth Blocked Ports
  2. Invalid TCP Destination Port
  3. Invalid TCP Source Port
In Norton you must also Deselect MS Windows H.323 BO (2) signatures on the Intrusion Prevention Signature Exclusions page of the Intrusion Protection Advanced Configuration

E-mail comes in all right, but I get the error message when I try to send messages out. . . says server won't accept my address


Some ISPs will block your ability to send mail via SMTP client on your machine. If the email server is different from the one offered by your ISP.

the typical port for the SMTP service is TCP port 25. To allow your outgoing email to route past your ISP, change this to TCP port 587.

On Linux and Mac OS/X, this is found in file /etc/services
On Windows XP, try 'windows\system32\drivers\etc\services'

Locate a line such as
smtp 25/tcp mail

and change it to
smtp 587/tcp mail # port for outgoing mail

Port forwarding


Hi Robert,

let's see if I can shine a little light on your confusion.
To the "port" business:
Ports are simply connection points for different softwares in a computer. You know that websites usually communicate on port 80. That means that port 80 has to be open in a firewall in order to get to a web page. If your port 80 in your firewall is closed - no communication is happening.
Let's say you host a webpage at home, but you don't want anyone to get there easily. You could choose another port (i.e. 801) and if you want to access the page from the road, you had to type "http://www.mypage.com:801" and open that port on your router. If you now want to give access to everyone, but don't want to change your server settings, all you have to do is to re-firect the traffic in your router by saying: "Redirect incoming requests for port 80 to port 801." (This is the public port 80 to the LAN port 801.)

Does this make sense to you?

So...your game on the Wii usually uses ports 28910, 29900, 29901, 29920, 80, and 443. If none of the ports is used by another application, then public and LAN ports are identical (no redirect necessary.)

And here we go:
  1. Open a web browser like internet explorer or Firefox. Enter the IP address of your router in the address bar of your browser. By default the IP address should be set to 192.168.1.1.
  2. You should see a box prompting you for your password. Enter your password now. By default your password is admin. Click the Log in button to log in to your router.
  3. Click the Firewall link.
  4. Select Disable from the Firewall Enable/Disable drop down box. Click the Apply button. Click the Virtual Servers link.
  5. Click the Add button.
  6. The Wii requires you to forward the 80,443,28910, 29900, 29901, and 29920. Go ahead and enter the settings into the Virtual Servers menu. It looks like this:

    IP Address: (your Wii IP)
    Protocol Type: TCP (to be safe: "TCP & UDP")
    LAN port: 80
    public port: 80
    Enable: (tick on)
  7. Repeat the "Add" command and put in all 6 ports.
  8. To open ALL UDP ports your range is 1 - 65535.
Don't forget to click "Save" when your done!!!

A couple more things:
  1. I would feel rather uncomfortable to open ALL UDP ports - it is like leaving your front door unlocked and every portscanner will find you wide open. But if you have to...
  2. To make sure that the IP address you entered for your Wii will stay always the same. you should edit the "DHCP Clients List". Look at your manual page 37/38 (if you don't have one, you can get it here.) This ensures that the ports are always forwarded to you Wii and not to your computer. (If you have questons about this - let me know.)
  3. And while you're on it: there is a new firmware out: version 2.06T13 from 2007. You can get it here.
    But ATTENTION!!! Little nasty line says:
    "Special Instructions: A reset back to factory default is necessary after firmware upgrade. You will need to reconfig after upgrade. Do not use previous config backup's after upgrade." - Make sure to upgrade BEFORE you change all the port settings etc. otherwise you will have ot do it again.
  4. There is a cool webpage to test if your port is open. Go and check it out: http://www.canyouseeme.org/
Oof...So - I think I've got everything... in case I did forget something or it is not clear to you, just come back and leave a comment and we look at it.

Good luck and enjoy!

Belkin 54 g wireless router....cant find on the net. need to port forward to host blizzard.net games HELP!


Make sure your private IP address is statically set.  Your public IP address is obtained from your ISP and is what other users will be connecting to.  You can not manipulate your public IP address so if your ISP is running DHCP, it is very possible that your public address is changing.  Also if you are frequently disconnecting your modem, it is possible your ISP is leasing you a new public IP address each time.  So try to keep things as static as possible.  As far as the battle net stuff.

Diablo, Warcraft II Battle.net Edition, and StarCraft: 
Allow port 6112-6119 TCP and UDP out and in
Diablo II: 
Allow port 6112 TCP out and allow established sessions in 
Allow port 4000 TCP out (realm games) 
Allow port 4000 TCP out and in (hosting open games only) 
Warcraft III: 
Allow port 6112 TCP out and allow established sessions in 
Allow port 6112 TCP in (hosting custom games) 
Allow port 6113-6119 TCP out and in (hosting custom games if you've changed the default port in the Options/Gameplay screen) 
If you are still having problems after you open up the required ports, try opening 116(TCP) and 118(TCP). I don't really know if these ports are required or not. 
I have had people tell me that opening up those two ports have helped them connect to battle.net.


Hope that helps.  For manipulating ports in your router I suggest consulting your user manual, or online FAQ.  Save your router config before applying any changes, and always remember, opening up ports subjects you to different types of security threats so be aware that is a risk you are taking.

No incoming and outgoing call


You may be behind a firewall or NAT. You can set an option that you are; if that still does not work, you may need to open some ports on the firewall.
Yahoo! Messenger uses a variety of ports.
Service Ports Chat & Messenger TCP Port 5050: Client Access only Insider/Room Lists TCP Port 80: Client Access only File Transfer TCP Port 80: Server Access.
Your ISP may block this port, as its used for web hosting.
You can change port in Messenger, Preferences, File Transfer. Voice Chat UDP 5000-5010
TCP 5000-5001: Client Access
If UDP Fails, TCP will be used instead, see below. WebCam TCP Port 5100: Client Access Super Webcam TCP Port 5100: Server Access P2P Instant Messages TCP Port 5101: Server Access
PMs between Buddys may not use the Yahoo! Server, but this is not a requirement.
