By tyhung ·
Dear Sir!
I have one server with ten client, 1 switch.
The server uses win2k adv.
I have 2 nics on this server, after configuring
2 nics i have problem:

Nic one:
ip 192.168.0.65
subnet 255.255.255.192
gateway 192.168.0.65

Nic two:
ip 192.168.0.129
subnet 255.255.255.192
gateway 192.168.0.65

Lan on Nic one: 192.168.0.66
192.168.0.71

Lan on Nic two: 192.168.0.129
192.168.0.134

server and client can not see each other .

hows the clients configured and what nic are they using to find the server?

change the NIC that does not service the LAN where the 10 clients reside on to a different subnet. e.g. if your LAN is NIC # 1 with ip address 192.168.0.65 subnet mask 255.255.255.192 . make the second NIC a class c 192.168.1.1 subnet mask 255.255.255.0
The second NIC would be WAN and is the default gateway out.

It looks to me like you have an overlapping address at 192.168.0.129
Change LAN on nic two to 192.168.0.130
192.168.0.135

First question: What's the reason why you need two NIC cards in the server? Do you need more bandwidth? For one switch and 10 clients? If you have 2 separate groups of clients, you better have 2 independent switches or, depending on switch model, use VLANs.

Second: You can not use your own address as default gateway, it creates loop. If you have Internet connection, put your router IP address in this field. If it's completely stub network, just blank that field.

Third: Your networks are not overlaping. But they are restricting client addresses.

Lan1: 192.168.0.65/255.255.255.192 -> 192.168.0.65-126

lan2: 192.168.0.129/255.255.255.192 -> 192.168.0.129-190

Your clients should have IP addresses in appropriate range according to which Lan they belong (if you have separate networks). And they should have same network mask your server has, or they will think server is on another LAN.

Good luck and keep it simple.

One problem is that you have 2 default gateways, but not really. Your computer really has only one default gateway for the computer, not one per NIC. The next thing is that 192.168.0.65 is not on the same network as 192.168.1.129/26 so deleting that gateway may be a good thing. You may need to add static routes through the interface that does not have the default gateway.
What do you mean by the statements Lan on Nic one and two? What are you trying to accomplish with 2 NICs in the computer?
