The most likely cause for this is a router, gateway, or firewall. Here is a summary of steps required to fix this problem.

---

1. First find out what you actually have. If you don't know yourself, ask the most knowledgable computer user in the house whether you have a router, gateway, firewall, or a combination.

2. Tell the same person what you want to do. Say something like "I'm having problems playing a game over the Internet, and support forums online tell me I need to change some settings." After telling them that, show them this following statement of what they need to do:

Open or forward ports 10052 and 10054, both TCP and UDP

3. Having someone else do this is the very best solution. In most cases, the person who set up the router\gateway\software will know the most about the configuration and how to change settings.

4. If the person who you are asking does not know how to change the settings or this particular setting, tell them to read the manual. The manual or documentation included is the best place to find out how to configure it.

5. If - and only if - nobody in your household has any clue how to do this, AND you have read the manual cover to cover and still haven't been able to figure it out, OR you've found out the correct way but it doesn't work, you should post here for help.

6. There is some information you do need to include when you post, which is very easy to get.

- Find out the manufacturer, name, and model number of your router if you have a router. If you don't know this, it will be right on the actual piece of hardware.

- Find out the name of your firewall program if you are using a firewall, or specify if you are using the Windows XP firewall

- If you are on a network, include the number of computers on your network, what operating system is on each (and specify which computer you wish to play JJ2 on), and if possible the IP address and gateway address on that computer.

7. Post your problem, and all this information, in this forum. The information is easy to get, so there is absolutely no reason why you can't get it, but if you can't, post as much as you can. (To keep clutter down, post as a new topic, not as a reply in this topic)

8. The people here will reply to your post, and will ask you questions and give you certain procedures to try. Answer these questions in detail, and give detailed results of the procedures. This is very important in quickly diagnosing and correcting the problem.

Notice that there was a lot of emphasis on reading the documentation and asking people who configured the network. This is because these sources are much more likely to know how to solve the problem than we are. The advice RTXM holds true (Replace R with "Read", T with "The", M with "Manual", and X with the emphasis adjective of your choice)
