Need a little help with my networking situation...

Hi all. I have an interesting dilemma here. I need to have my server (win 2000) connected to this one (win xp) by x-over cable, and this connected to the router, and the router to the internet.
For all you who didn't understand, heres a crude visual:

Code: Select all

R
+--+--+--+ 
C  C  C  C
   x
   C
R is the router, C is a computer, x is the xover cable.

So far, I have this connected to the router, the router to the internet and the 2000 to this one. The only problem is that this computer needs to pass along tcp/ip connections b/t the 2000 and this one. Follow? I can share files between the 2000 and xp, but the 2000 can't connect to the internet, handle requests, etc. How do I get this computer to do that? I've done loads of research but I can't seem to find anything.

Is the router only a four port?

No, its 5, but 1 is used for router -> modem, 1 for this computer, 2 for other computers, leaving one which I can connect the server to, but because of the way the room is set up, plugging it directly into the router means an unsightly black networking cable running across the middle of a room. It works for short periods of time, but I'm looking for a more permanent solution that doesn't involve drilling holes in the floor or buying a 50 foot length of cable to go around the contours of the room, and since this computer is 5 feet away from the server, and I have a 5 foot xover cable, this is what works.

You have to start "Internet connection sharing" service on the PC with Win XP. You may also find it more appropriate if you connect the Win 2000 PC directly to the router.

So the modem uses a normal hub connection, not the WAN port on the router? ... you have a glorified hub then. All the computers aren't protected by the router's firewall or almost anything the router provides.

~feyd: I'm not sure, when I checked it at first, I just glanced at it and counted ports. I think it would be, since our router has very good firewall capabilities that appear to work.

~VladSun: Would you please explain how to utilize internet connection sharing. I tried that before and it didn't seem to work, so maybe there's a setting I missed, etc. Also, I mentioned that although I can connect directly (and have before, successfully), the cable runs across the middle of the floor, I am trying to avoid most methods used to hide the wire, and don't have a wireless network (although it would be nice :D)

If you have access to it at this time, please check to verify the physical configuration.

If all else fails, I suggest using a small (passive) hub rather than connection sharing. I've had enough problems with connection sharing being temperamental that I've given up on it.

Go to "Control Panel" -> "Network Connections"
You will see a list of Local Area Connections including the LAN card connected to the win2000.
Right-click on it and choose properties. Choose the "Advanced" tab.
You will see "Internet connection sharing" ;)

~feyd: Yes, it's connected by a WAN port.

~VladSun: That sounds like it would do it, but when I check the box, it tells me theres already a 192.168.0.1 on the network (It's the router), and that this computer must be the only 198.192.0.1. So, If I change the router's IP address, what settings would I have to change where and on what computers?

So then it's a 4+1 (hub+wan), correct?

Yes, 4+1

Stupid Windows ...

From http://www.practicallynetworked.com/sha ... /index.htm

"...However, XP ICS is missing some features of those earlier versions. You can't disable the DHCP server, change the server computer's IP address, or change the range of addresses allocated by the DHCP server..."

Switch to Linux ;)

So, you may try to change you router's setting - e.g. make it 192.168.1.1. You should also check if the router has its DHCP service on - if it is on, you should only restart your network (the simpliest way - restart your PC). After that your WinXP PC shoud have been assigned an IP address. Now, you can continue with "Internet connection sharing" service.

@Feyd: Just to be precise, I don't think that it is "hub", rather it is "switch". Nobody uses hubs nowadays.

I never said it was a hub. However that is the easiest illustration for most when referring to the cluster of internal connections on a router/switch.
