I have two windows 2000 domain (one windows 2000 server for each). One of them is 192.168.1.0/24 and the other 192.168.4.0/24. They are in the same location and they are all attached into the same 3com switch. The problem is how can I connect these two network. Do I need a cisco router or just change some settings in the Windows 2000 RRAS can resolve problem. Could anybody help me and tell me how to do? Thank you! Appreciate for any Help!

I also know the client in these two networks cannot ping each other because of the network ID. I don't want change my ip address setting's because I need two networks logically. What I am wondering is do I need a router or change the settings in RRAS for the server. If I need to use RRAS then do I need another server with two NICs to act as a router or I can still use these two (only, one for each domain) domain controllers to route the network traffic. Thank you!

Physically speaking, you got one network. But, logically, you have two. I would suggest to get another switch and physically divide the two networks. Once that is done, you could add a NIC to each of the servers and then run a cable between the new NICs. After that, enable RRAS on each server for routing among the two physically separate networks.

Alternatively, a very simple thing to do would be to move to a Class B IP address space and use /16 as the subnet mask. I think that should work.

I hope this helps!!!

You can plug both networks into 1 swtich, it is allowed.

But there must be a machine to act as an interdiary on the switch/hub.
(No it does not need to be a cisco router, any machine with 2 nics that can do IPForwarding can be a router[linux, nt4 wkstn and srvr, 2K srvr, etc]

That machine would need 2 netwk cards, and each of the connections needs to be plugged into the switch/hub.

Again it can be the same switch
It is not elegant but it will work.
(you usually use 2 switches/hubs in order to segment the physical traffic; but if it is a small netwk 1-10 devices, you can theortically put all 10 devices on the same switch, when arp does a broadcast, only those devices on the logical netwk will answer)

In rras you need to set up routing between the 2 interfaces. This is a pretty straight forward process.

Thanks of all your reply! I know I can set two or more IP address in one NIC adapter in Win2k. So what does it for? Is it possible to set two ip addresses for each server in it's NIC adatper then I can route these two networks? Thank you!

by lordinfidel

You can not assign 2 IP's to the same adapter and route between the 2.

That's not the way it works.

Generally when you assign multiple IP's to a nic (which is valid) it is generally for running multiple services on a system that require a unique IP. WebServers are a perfect example of this.

In order for routing to work, you need 2 nics and IPForwarding enabled. In 2K this is thru RRAS.

(a easier way for you, www.bbiagent.com - see my post titled- DSL readers and consultants read)

Hi Loadinfidel:

Thank you very much for your detailed timely reply. I'm very appreciate for your help.

In my openion if u use cisco router and make router's interfaces as part of both the networks,u can communicate (connect)these systems each other.By manipulating RRAS settings also u can communicate with each other but iam not well versed with that procedure so i can't provide solution in that perspective.
Hope it helps for u..

Thanks,

Hi Hemant:

Thanks for your help. I think I can use a PC with two NICs act as a router or use a real router, is that right? Very appreciate for your help!
