Subnetting with nt network

By raj_ti ·
I have networking of 100 machines with class C IP addressing. Ntserver has IP address 192.168.100.2 with only one network card. Other workstation is 192.168.100.3,4,5.e.t.c.
Now we decide to divide the network into two subnet. So I put another network card in my Ntserver.I assign the IP address in ntserver 192.168.100.65 to first network card .168.100.129 to second network card. Subnet mask for both cards is 255.255.255.192.
I also enabled the IP forwarding option on ntserver. Other workstation IP address for first network card is 192.168.100.66,67 up to 127. & Subnet mask is 255.255.255.192 for the entire machine. The same way second subnet workstation IP address is 192.168.100.130,131,132 up to 191. & Subnet mask is 255.255.255.192. But any of one network is working at a time. I am not able to ping each other network from workstation.
Where I am wrong I did not get.
I need some solution very urgent. If you help me I am very thankful to all of you.

Thanks

If you are looking to segment the traffic on the network you can give onecards on the server and half the network:
192.168.100.x
255.255.255.0

The other card on the server and the other 1/2 of the network:
192.168.101.x
255.255.255.x

Enable IP forwarding

I would change the IP addresses of the Server so that it is inside the Subnet range of 64 to 191. e.g 192.168.2.100 and 192.168.2.180 In my opinion IP addresses above and below range 64:191 are illegal with a 192 mask. (255.255.255.192)

Subnetting with nt network

It looks like your subnetting is done properly, so possibly the problem is your default gateways. The NIC w/address 192.168.100.65 ("subnet A") on your server needs to have a default gateway of 192.168.100.129, and the NIC w/address 192.168.100.129 ("subnet B") needs to have a default gateway of 192.168.100.65. This enables the server to work as a router between the two subnets in order for the computers in each subnet to be able to find each other. Your workstations in "subnet A" need to have a default gateway of 192.168.100.65, and the workstations in "subnet B" need to have a default gateway of 192.168.100.129. Hope this helps!

Synergy has your solution except for the adding of the a default gateway address on the server. The server is acting as the router and since is connected to both subnets needs no default gateway. All networks are known to it and so it needs no address to send unknown network IP pakcets to.

Also multihomed computers must only have one default gateway if needed. If your server was also connected to the internet then a default gateway address would be needed on the internet interface.

The workstations are the only systems in your configuration that need a default gateway.
