I am trying to host games on Starcraft and everytime someone tries to join it gives them the stupid Latency error. I was wondering if someone else has had this problem and fixed it. Here is some info I think you may need to help me.

Currently using a LinkSys Wireless-G Broadband Router.
Model: WRT54G

I have read on the blizzard website about port forwarding port 6112 but that didn't resolve the issue. Please help!

Make sure you're forwarding UDP traffic for the port. Common mistake is to forward TCP instead. You must have UDP.

Can you be more specific? Why can't I just forward both?

You can forward both. Bottom line is it must have UDP being forwarded. Forwarding TCP as well slightly reduces security insignificantly.

After doing that I still can't create joinable games.

In Norton Internet security, which bits need to be enabled on the firewall?

To both, you need to make exceptions in your software firewall as well to allow incoming connections. This will be different depending on the software firewall you use (if any).

ok i had the exact same problem, with me it was the firewall in my router. To turn off the firewall do this.

1. Start menu
2. Click run
3. Type cmd (i know this might seem simple but im just being specific to make sure you get it)
4. In the black dos box type ipconfig
5. Note your default gateway and your ip address
6.Open any web browser and type your default gateway into the address box.
7. A password screen comes up, or you goto a website. If a password screen does come up youll have to google your routers default password. Lyksis' is blank for a user name and admin for the password.
8. Now you need to find something called dmz, its under gaming and apps for lynksis.
9.Once found type the last group of digits of your ip address into the appropriate box, enable it and save/apply settings.
10. Logon to bnet and host a game, make it interesting so people want to join i reccomend something like can you join?
11. Problem solved.

And you potentially open up new massive problems.

Do not do the above unless it's a last resort. This opens your computer to every port directly to unsolicited incoming traffic, and can result on your machine being hacked in a matter of minutes.

Try like heck to use port forwarding and make exceptions in your software firewall first. If you must use DMZ, I would suggest the following:

Vigilantly patch your system.
At the very least, make sure the Windows Firewall is enabled. More preferably, use a better software firewall such as Kerio or Zonealarm, or others.
Unbind File and Print Sharing on your Network Connection Object in Windows.
If you have personal information on your computer, if you can, move it off to another computer.
Avoid if possible doing things with personal information on this computer, such as logging onto online banking sites, typing sensitive user names and passwords, etc.

I highly recommend NOT doing the DMZ solution!

"Enough, enough bowing down to disillusion!
Hats off & applause to rogues & evolution!
The ripple effect is too good not to mention.
If you’re not affected, you’re not paying attention!"

Wait I missed that last part about DMZ mode. Do I enter in my private IP address, or my public IP address? Or none? I don't know what to type in.

Private IP.
