A_B_Danner -> LAN games & Serial Numbers (2/18/2007 9:25:02 PM)

I'm trying to play a LAN game against my 16yr old son (get him off WOW and onto a real game). We are having a problem connecting (it won't).

The games are both using the same serial number, as i've only purchased one copy. Could that be the problem, or something else? Do i need to purchase another game to make it work? I don't actually mind, but wanted to make sure he liked it prior to plunking down another $40.

Firewalls are both off in Windows, and the ports are open on the Linksys, althought i don't know if the ports matter in a LAN game.

Thanks Matrix - keep the CC series alive.

Can both pc's ping each other?



Andrew Williams -> RE: LAN games & Serial Numbers (2/18/2007 9:53:53 PM)

At what point can't you connect.

1. you both launch game
2. you both go to multiplayer screen
3.you both hit tcp/ip button
4.One of you hits host and waits for connection
5. the other (client) hits Host IP and enters the Hosts IP address in the BOX
6. The clients PC searches for available games
7. The hosts game appears and the client clicks on it and hits "Join"
8. Host selectes a game to play
9. Both players hit ready
10. Host hits next and both players move on to reqisition screen



A_B_Danner -> RE: LAN games & Serial Numbers (2/18/2007 10:15:57 PM)

we have good ping.

The game locks up after the joining computer finds the game, and clicks <JOIN> It locks up at that point. Up to that point is fine.

thanks for the help



e_barkmann -> RE: LAN games & Serial Numbers (2/18/2007 11:47:40 PM)

are you connected wirelessly by any chance? Wireless can have trouble with dx games I have noticed.



A_B_Danner -> RE: LAN games & Serial Numbers (2/19/2007 12:17:50 AM)

not wireless, all cable connections.  I guess we could try to connect via battle hq, but that seems kinda silly.



Beeblebrox -> RE: LAN games & Serial Numbers (2/19/2007 1:46:45 AM)

Assuming your LAN is a trusted Network (normal for LAN) and firewalls switched off, and the 'Client' can see the Host's game, then you have established a connection.  When you do the Join, all the Port issues will kick in, but again this should not be an issue on a LAN, so [&:]

How is your LAN setup for the 2 PC's.  Do they have the same subnet and default gateway?  I would suppose you have used the DHCP service from the Linksys to allocate Network configurations?  If not, how is the TCPIP set up for each workstation?  Although I think it unlikely on a small LAN to have issues here, it will help elimiate potential problems.

For example, what are the TCPIP Number, Subnet Mask, and Default Gateway for each workstation.  Are you able to share Resources from 1 workstation to another?  What level of TCPIP are you using (Adapter Properties)?  XP includes TCPIP 6 and I am not sure if that works with COI.  Are  you using any other Protocols bound to the Adapter? i.e. IPX/SPX...

Sorry it sounds a bit of a mouthful, but knowing the network is configured appropriately starts narrowing down the options, and appreciate you patience.

Is the Linksys being used as a Router and/or Switch (Network 'Hub')?

Are you entering the external IP of your router on the WAN or the internal IP of your machine on your LAN?

All you should have to do is determine the LAN IP of the host machine:

1) go start->run->cmd

2) from the command prompt type: ipconfig

3) The ip address result will be 192.168.x.x (where x is one or more numbers).

4) Have the joining machine connect to that IP (not the IP of the router).

We do get this far before the freeze

"How is your LAN setup for the 2 PC's.  Do they have the same subnet and default gateway?"

Yes, same subnet & gateway 

"I would suppose you have used the DHCP service from the Linksys to allocate Network configurations?"

Yes

"For example, what are the TCPIP Number, Subnet Mask, and Default Gateway for each workstation.  Are you able to share Resources from 1 workstation to another?" 

Yes, able to transfer files, share printer,etc.

"What level of TCPIP are you using (Adapter Properties)?  XP includes TCPIP 6 and I am not sure if that works with COI.  Are  you using any other Protocols bound to the Adapter? i.e. IPX/SPX..."

Don't know

"Is the Linksys being used as a Router and/or Switch (Network 'Hub')?"

As a Router.

Seems like it should be pretty simple at this point. The computers Ping each other. Each computer is assigned a seperate IP Address by the Router - 192.168.101 and 103. These appear on the multiplayer as they should. The one computer can see the game on the host computer. When <join> is pressed, the game freezes.

Those don't look like valid IP addresses.

Did you mean 192.168.1.101 & 192.168.1.103?

Beeblebrox -> RE: LAN games & Serial Numbers (2/19/2007 4:04:53 AM)

Well that seems to clear up some stuff, and thanks for the detailed replies.

I will continue with the issue of Protocols.  I have found that having multiple protocols bound to an interface can casue connectivity problems.  If you are running XP pro on both machines and have used the defaults for any setup, then it is unlikely this will be the case.  You can go to the Properties of the LAN Adapter on a workstation, and see the list of things that are bound including Protocols.  I am assuming both workstations are XP?

If the Linksys is not being used as a Switch, then what is?



KWP -> RE: LAN games & Serial Numbers (2/19/2007 4:59:28 AM)

Does this LinSys router allow you to enable/disable Filter Internal NAT Redirection. On my BEFSR41 V3 it is found under Security/Filter.

You might want to try disabling it:

quote:

Filter Internal NAT Redirection allows for internal network to access a server in the LAN. Select Disable to allow local PCs to access local servers like FTP, WEB, or others. Select Enable to prevent local PCs to access a local server. By default, the option is set for Enable.

IP addresses:
192.168.1.101
192.168.1.103
IP addresses issued by linksis router, so they may change but show up when the mulitplayer screen comes up.

I've never dealt with a network to any depth, so this is becoming an education. Opening up the ports for BATTLE HQ was the first time i've ever had to deal with the linksys directly - but it was quite straight forward with the linksys website instructions.

I guess that the linksys is acting as the swtich since it is assigning IP addresses?

"Filter Internal NAT" - and this is what language? I guess I'll give it a go tomorrow. It will be fun to play agianst my 16yr. old if we can get this working. He is under the impression that a few years of World of Warcraft has made him a tactical genious. We'll see.

Your router is dishing out IP addys through the range of 192.168.1.101 thru 192.168.1.150. It's doing so because that's its default setting. You never want to turn its DHCP feature off, btw. The problem with it's ability to communicate with Windows and assign IP addresses is that occasionally it throws you a curve. Tomorrow, when your systems are booting it may assign the addys differently and wreck any sort of port-forwarding that you've done. A nifty guide that explains how to avoid this problem can be found here:

http://www.speedguide.net/read_articles.php?id=177

A SWITCH is different from a HUB. Hubs are dumb. They just divide up bandwidth according to the capacity of each port on the device. Switches are smart. There's a little feller in the unit that directs incoming and outgoing packets to the correct IP. That way you don't lose bandwidth because it's been hacked into fractions by the method employed by hubs.

NAT is network address translation. It's a wonderful technology because it makes your LAN appear to be a single system on the WAN, one with a single IP addy. EXCELLENT security for that reason, especially if no doors (ports) are open on it.

The problem with NAT is that it can foul up games pretty severely. The answer, while problematic, is to "port-forward" certain doors to a selected system on your LAN. Not all routers/switches/gateways (interchangeable terms) can be configured for port-forwarding.

In reference to "Filter Internal NAT", it's a reference to the ability of YOUR model of router to do the same sort of number on internal LAN traffic that it's doing on the WAN. It can hack up something like game traffic on your LAN.

Finally, I try not to run extra services on my home LAN. Stuff like File and Print sharing, IPX and QOS have been removed.

Did any of that make sense?
