Firstly, I am sorry to irritate you with another topic about hosting problems. I have looked around for ways to solve my problem for several weeks, and came out unsuccesful.

Basically, whenever I host I ping to others and they can't join.
Many people say this is because of a firewall, and I do have one. I have tried disabling it and then hosting, but still I pinged. I have cable, and a router (Called HP Gateway or something). I am sharing the cable and router with my dad's computer as well. Feel free to ask me any questions that you think may be useful in the process of solving this problem, and once again, I apologize for irritating some of you into doing research on this problem, but hosting is an important part of playing jj2 for me. Without hosting, I cant beta test my levels online, host duels or levels and that kind of stuff. Anyways, thanks in advance and hope this gets solved.

Let me try and get your network configuration right before I try and help you:

Your cable modem connects right to the router, and all the computers on your network also connect right to the router?

You have disabled all software firewalls?

What operating system are you using?

What is your internal IP address? (Probably starts with 192.168.)

1. Yes
2. Yes, unless there are some that are hidden very well and I don't know about them, which is highly unlikely.
3. Windows 98
4. Can't people hack you if you give away your internal IP adress. Also, no, I doesnt start with 192.168.

Only those on your network can affect you through your LAN IP address, which is what Link is referring to.

By default, this number is usually 192.168.x.x, where x is a varying number.

Go to start-run, type in winipcfg.

Locate your network adapter in the list of adapters. Look at the default gateway, and write down the number. Look at the IP address, and also write down that number. Now type in what you saw in the default gateway box into your browser window's URL box. You may need a password to enter your router's configuration, and this fact varies by company. I could give you specific instructions if you have a Linksys router, but otherwise, you will need to refer to your manual to figure out the password and where the port forwarding options are.

Once you have gotten into your router's configuration page, locate the page where you can configure port forwarding. Type in the IP address you got from the "IP address" box in winipcfg, and set the range to ports 10052 to 10054, with TCP and UDP protocols both enabled for forwarding. Save these settings and try serving.

I have heard that some routers fail to forward UDP, which is an extremely bad thing for a router. We might be able to help you further if you provide the name of the brand of your router. Good luck.

The only problem with that is that I can't locate the page to forward ports.

That's what Derby was telling you how to find. Go to http://ga.te.wa.y in your web browser (replace ga.te.wa.y with the actual address of the gateway found using Derby's method)

If there is no configuration page there, or you get an error, you have to find out yourself how to configure the router, which will be in your router documentation. If you do not do that, we cannot help you any further.

I have 10052-10057 forwarded. Maybe I'm just being safe though.

Ok, I went there and found the forwarding page, when I looked i saw ports 10052-10057 in the forward list for both TCP and UDP...

Are they forwarded to the right computer? Make sure they are set to forward to the internal IP of the computer you want to play JJ2 on.

If that doesn't work, and you're sure it is set up properly, then either you have more than just the router blocking you, or your router is a bad router that doesn't do what it is supposed to.

You have to figure out your network IP. You have Windows, right?

uh... I was going to show you where to find your network IP, but now I forgot. *feels stupid*

sorry.

Thanks guys, now I can host on my own computer (My dad wont let me host on his..) Anyways, thanks for all the help everyone!

I'm glad you got it working
