Having it connected to the network but not internet

[Cohen]

Hey guys,

I have setup a spare computer that i have had at home as a small home server.

Now, it's not a normal home server. It's a computer that i has iTunes open all the time and shares the music as a library and then my family can connect via the network and gets songs they would like.

I want it on the network so i can access it, but has no access to the internet.

How can i do this?

Thanks,

Cohen

Are you using wireless for your home network? If so, your network is one that gives all your machine access via WEP/WPA authentication. Once you are able to connect to your wireless network, either all or no machine can connect to the internet (provided you haven't made any filter changes on your router).

If your home uses wired networking, and you want to create a simple network to share files and internet, it's not hard either. There are countless tutorials on how to set up a simple network...consult google.com if you don't mind.

One way to have the server connected to your network without also connecting to the internet would be to use a networking protocol, such as IPX/SPX, that isn't internet-compatible. All computers accessing the "server" would need to be running the protocol and in the "server" PC, you would have to disable TCP/IP.

I know IPX/SPX can be installed in 98SE, XP & Vista (because I've done it), but might have to play about with 7

How do i go about IPX / SPX??

The server is on the wired network, and we have wireless which my dad & I use, as well as 2 iPod touches within the house. So i want each device / computer to be able to access the "server" via the network but not have the server connected to the internet.

Not knowing what router you have it maybe possible to create a firewall rule that just denies all outbound traffic from your "server", assuming your server has been setup with a static IP address.

 

[Cohen]

I can't get the firewall part to work.... maybe i am doing something wrong. I have a netcomm router.

I suspect you may have run into the buffers before you start. IPX/SPX can be installed in your computers, but iPods (about which I know nothing) will probably be the stumbling block. If they can only use TCP/IP protocol, it isn't going to work.

Install IPX/SPX in Windows Vista & Windows 7

[Requires: that you have Windows XP (SP2) in another PC]

1)
Create new folder named 'temp' in the root of your Vista or 7 drive ( C: ).
Copy the following files from XP (or expand from XP CD) installation:

Windows\System32\drivers\nwlnkipx.sys
Windows\System32\drivers\nwlnkflt.sys
Windows\System32\drivers\nwlnkfwd.sys
Windows\System32\drivers\nwlnknb.sys
Windows\System32\drivers\nwlnkspx.sys

Windows\System32\rtipxmib.dll
Windows\System32\wshisn.dll
Windows\System32\nwprovau.dll

(Following folder is hidden)
Windows\inf\netnwlnk.inf
Windows\inf\netnwlnk.pnf

to C:\Temp,
and to corresponding Vista or 7 folders.

2)
Go to the “Network Connections” folder (“Start > Run”, type ncpa.cpl and click OK)

Right-click your LAN connection and select Properties.

Click Install..., select Protocol and click Add...

The NWLink IPX/SPX/NetBIOS protocol may be listed on the Network Protocol list.

DO NOT SELECT IT.

Click Have Disk... Browse to C:\Temp. Select netnwlnk.inf.
Click OK.
Select NWLink IPX/SPX/NetBIOS from the list.
Vista/7 will tell you that the publisher could not be verified.
Click Install.

If all goes well, the protocol should be now installed.
Restart computer.

If necessary, I can let you have the files from XP.

Not sure if this would work on win7 - but one thing to try is to set the default gateway on the server to itself, (127.0.0.1), this should prevent the system from accessing the internet, whilst retaining access within the local subnet.

That should do the trick, a nice simple workaround with no need to create rules or install software. Good thinking

Just curious how do u intend the devices to connect to the server via the network as you have stated? In all instances you will need an IP address for the server, as already mentioned you could give it a static IP, subnet and default gateway. However if you wish to connect to this server over the network and wirelessly via your router (i would assume), this could be a problem, as the router does would not have broadcasted the network that the server is configured with. Most likely you might need to configure your router to broadcast this address.

Doesn't work - it says that that address is reserved.

It looks for the iTunes library.... regards what the IP etc is...

And the other computers just look for the server name - Server-PC there for the address being \\Server-PC\Sharing Folder\Music

You can only mapp drives/connect to shares if your machines are on the same vlan. If your server is wiredly connected to your modem/router, and your other devices are to wirelessly connected to your server, then 1) the server must have a wireless network card in it, correct? If so, you will need an access point (a.k.a, a router to broadcast the server's network) otherwise, i'm not sure how one wireless card can simply connected to another. Or 2) you must setup your router (which the server s connect to) to broadcast the network which the server is configured on inorder for your other devices to pick the network up and connect onto it.

OK you can obtain the same result by using the actual manual server IP address as the default gateway.

Is it just me or is "aem" confusing the living daylights out of you all too?

 

[Cohen]

aem - your wrong.... you can access files on a wired network wirelessly as long as the settings are correct.

Technically a network requires a minimun 2 pcs, If you have a server connected to a modem by wire, that to me is not a network. You may be on your ISP network but interms of your own home network, you haven't got one yet. So to be able to access your server ie connect to the shares on it, you need to connect/ping it. Right? How do you intend to do this? does your server broadcast it's IP wirelessly for your other devices to pick up?

So far we only have a server wired to the modem (i assume), and other devices which wants to connect to this server through wireless connections.

 

[Barman58]

There is a network of 2 PCs connected to the broadcom router either wirelessly or wired.

the requirement is to connect a server to the existing network but to deny the server access to the network.

One example of a system that should work is this
Router IP 192.168.0.1

PC1 IP 192.168.0.2 gateway IP 192.168.0.1
PC2 IP 192.168.0.3 gateway IP 192.168.0.1

Server PC IP 192.168.0.255 Gateway IP 192.168.0.255

The two PCs may have their IP set by DHCP from the router as long as the server address is excluded from the DHCP pool

A picture is worth a thousand words. This according to Barman's instructions. Hope this helps to clarify any confusion. Just another $0.02

This is exactly what i am trying to get to.

The IPs of 192.168.x.x are part of the router's setup (Linksys IPs), they are not provided by your ISP. In other worlds, setup your router to enable DHCP, and allow your machines to auto detect IPs and you will have 192.168.x.x in your ipconfig details.

With a wireless router broadcasting the network, everything falls into place. As for restricting the server to again access to the internet. Many ways to do this, but i don't see the need to do this, why would you?

Ps I have only used static IP in a peer-to-peer networking between two PCs (with crossover cables).

The reason i want it not to access the internet is i think it is using bandwidth at night.....
