Subnetting

[Guest]

I have a network with a only one segment
To reduce traffic I want to divide it into 3 subnets.
Of couse I will have to use a W2K for Routting and connect this 3 subnetts
Can this only one router be a central router with 3 NICs? Will it be able to connectting this 3 subnets

The fact of the clients computers constantly access files and resources on the remote subnets and consequently pass through this central router, will decrese the network performance

Thanks

Yes you can install 3 NICs on the Windows 2000 Server and then configure
RRAS to make the server a LAN Router.

You should be able to do this fairly easily Ricardo. Check out

There is some great information there.

Yes, you can connect these three networks using one machine with 3 NICs. This is only supported in Windows 2000 server
edition though. W2k pro will route the traffic but it's not a supported configuration. Yes, this will slow things down if they are
having to go through the router to get there. How much slower it will be all depends on how much traffic is going through the
router. This is something you'll simply have to play around with to see if the performance is acceptible.

For information on how to enable routing on a Windows 2000 machine, refer to 120642 TCP/IP and NBT Configuration
Parameters for Windows 2000 or Windows NT http://support.microsoft.com/?id=120642

And yes, but why do you want to do this?

IF you choose to subnet, then you should do so on the
basis of the traffic patterns in your network or you might
makes things worse -- and spend more time getting it that
way.

OK. I want to create 3 subnets because almost all the clients computers access files (pictures and texts) in a only one file server, and it become the network slow. So if I create 2 subnets the trafic won't be isolated because of this file server
By creating 3 subnets I can put this file server on this third subnet and isolate the two others. The traffic will be high, but only on the subnet with the file server

If you have a different soluton for my case, please send me

Thanks

No, because then you bottleneck through the third subnet
(segment really, subnets without separate hardware segments
will do you no good here) for every request from either of the
other two subnets.

Define "high"? Have you looked at the traffic with a sniffer
(netmon, ethereal, windump etc) or are you just guessing?
SysMon/Perfmon might help too.

Will clients also be talking to each other (much?)

Look into upgrading your switch or switches. You can get a switch for less than $150
as shown in the link below that will allow the server to have a 1 gig nic and link to
the switch. More advanced switches, such as managed layer 2 switches can do a lot
more including vlans to isolate broadcast domains, securing access to ports by mac
address and 802.1x authentication, and network segmentation by isolating traffic
based on ports. You could get something like the Dlink 3226SM and the matching 1 gig
module for around $700. --- Steve

Yes, clients exchange files to each other but not too much
The traffic is more significant when with the server. All clients of this department works with pictures, that's why the network becomes slow sometimes
