Routing vs Bridging

[Andreas B.]

Hi folks,


hope someone of you can help me.

I'm trying to get Routing to work for me, but I can't
figure out how to set it up.

I've heard that the "Bridging" feature that comes with
Windows XP is also downloadable for Windows 2000 Server,
is that so?

I have tried searching for Network Bridging in the Windows
2000 areas but found NULL.

Anyone who care to help me?

Best regards,
Andreas

Windows 2000 (server) has the ability to "bridge" two
different network connections together. What is actually
happening here is that you are using the box as a router
with two different network IDs used. One for each network
connection. You will be forced to use NAT with this
connection due to the fact that one of the network
connections, the inside one, will be a private number.
Typically a 192.168.x.x number. I have my system at home
running this configuration and it works really well.

To activate it, right click on the "network neighborhood"
and click on "properties" You should have two network
connections listed. If you don't then you can't bridge.
All you should be able to do is right click on the
connection that you will be sharing the internet from and
go to "properties". You should have a tabe at the top that
is called "sharing". There is a check box there to enable
connection sharing.

You should be able to do a search for Internet Connection
Sharing on Microsofts web site or even the help within
Windows 2000.

I hope this helps.

This is NOT bridging. Bridging is a new feature of Win2003.

When you bridge you end up with ONE "broadcast domain"
and/or a SINGLE "subnet".

You have described ROUTING above -- only routing is built
into Win2000.

Thank you Rich!

The information was good to learn, but
it didn't help me.

The thing is that I need "routing" because I really
got three (3) different subnets on my network.

LAN 1 - Is the net via ADSL modem (static IP from ISP)
LAN 2 - Wireless LAN (wireless gateway/router/switch)
LAN 3 - With NIC's connected via a switch

The setup is following:

LAN1
====

ADSL Modem connected to D-Link Wireless Gateway/Router.
The static IP from ISP let say it's a.b.c.d.


LAN2
====

The Gateway/Routers (GWR) internal LAN is 192.168.2.x.
The GWR has IP 192.168.2.1 defined to the local network.

Now there are to boxes that has Wireless NICs. One laptop
with IP 192.168.2.6 and one Win2K Server (AD server) with
IP 192.168.2.2. Both have the follow TCP/IP config:

IP: 192.168.2.2 (Server01)
NM: 255.255.255.0
GW: 192.168.2.1 (the Gateway/Router)

IP: 192.168.2.6 (Laptop)
NM: 255.255.255.0
GW: 192.168.2.1 (the Gateway/Router)

Both these computers can access the internet!

LAN3
====

My LAN3 has the networkmask 192.168.3.x.
Following computers are connected to this net.

IP: 192.168.3.1 (Server01 that also has Wireless NIC)
NM: 255.255.255.0
GW: 192.168.3.1 (Don't if this is right?)

IP: 192.168.3.2 (Server02)
NM: 255.255.255.0
GW: 192.168.3.1 (pointing to Server01)

IP: 192.168.3.3 (Workstation)
NM: 255.255.255.0
GW: 192.168.3.1 (pointing to Server01)

The thing is now. I want Server01
(192.168.2.2/192.168.3.1) to be able to route between
these two networks.

I want the Workstation (192.168.3.3) to be able to
access the internet (cannot do that now) and also
be able to access the Laptop (192.168.2.6).

I have figured out that I must use Routing on the Server91
box, becuase it is the spider in the net.
But I dont know HOW to Route!!??

Someone with a generous soul, help me!!

Best regards,
Andreas

Do you have a (manual) router from the first (adjacent to the
Internet) router to the most interior network?
