Router help needed quick!

[schueymcfee]

BT have just upgraded our internet to 1mb.

To do this they changed our IP address - they have sent us the new ip address, but where do we change this on our server?

We have an internal IP address for our network, but we can't find any other IP addresses.

Is it on the router some how? and how would changing our IP address allow us to have internet access again?



thanks

It may be, depending upon how BT do it you might not need to change anything.

I've fixed IP here, but don't need to explicitly tell my router, as it picks it up when connected to my ISP.

Problem is, we've lost our internet and they say we need to change to these new IP addresses we've got.

I assume that you have a PC somewhere that has 2 network cards in it, 1 connected to your internal network and 1 to your internet router?

Did BT send you a single IP address or a small range of them?

Ah, bit more complex then I'm afraid. Do you run the router off a network hub, or connected to a specific PC/server?

They sent us 5, different ones.

Router is connected to a server.

Right then, 1 will probably be already allocated to the router remotely by BT, so pick one of the other ones and change the IP address of the card that's connected directly to the router (not the internal network).

Hopefully that should be enough.

Excellent, yes one is reserved for the router.

My next problem is accessing the right network card.

I can only see one in device drivers.

I'm using Terrapin Multinet BTW.

Which o/s are you using?
With most recent flavours of Windows you'll be able to right-click on "Network Neighbourhood" and select "properties" to see a list of network connections.

All there is is "My Network Places" which has "Make New Connection" and "Local Area Connection" inside.

If I look at the TCP/IP settings in Local Area Connection it accesses the Broadcom network card.

There are two DNS IP addresses in there.

Also, we're running Windows 2000 Server

Seems that that particular machine only has one active NIC in it, then. Are you sure that its the one that's handling your internet connection via the router?

We're running Windows 2000 Server.

I didn't set this network up, so I'm not really sure how it would connect to the router.

What other ways would there be without an NIC card?

[pdV6]

Its not USB is it?

[schueymcfee]

It's an ethernet connection.

That is the only machine inside the "server room" we have.

It has a router, modem and firewall all stacked up next to it.

[pdV6]

Ah - the "router" I was referring to is the internet router, i.e. the modem.

Sounds like the modem itself is connected to the main network router rather than via a machine acting as a proxy server / firewall.

Therefore, what you probably need to do is look at one of your client PCs. Open IE, goto Tools-->Internet Options-->Connections-->LAN settings and look to see what name or IP address is listed in the Proxy settings bit.

Is this your modem's old IP address?

No, it's just our regular internal IP address.
But the I think it is set-up as you've described - it looks like it.

OK - so the machine that that IP address refers to is the one controlling your internet connection. Is that the one you thought it was?

Erm, I checked the IP on my machine which is an internal IP. I then checked the IP on the server and it is the same.

The IP address of the server is the same as the IP address in my settings on my machine.

[pdV6]

But is that IP address the IP of the network card in your server machine, or some other one?
