2 Network Ccards On A Server

By teo ·
I have 32 users conected to a nt server 4. I wanted to segment the users in the following configure :

Group A : 16 users

First network card :

ip address : 191.168.1.64
subnet mask : 255.255.255.240

Group B : 16 users

Second network card :

ip address : 192.168.1.80
subnet mask : 255.255.255.240

Is the above configure all right ?

Should I configure group A as 192.168.1.64
and group B as 192.168.2.80. Both without subnet mask

Regards,

I could be wrong but they look like two different networks to me. Why not use a mask of 255.255.255.0 for both and for net A use 192.168.1.X and for net B use 192.168.2.X. If this doesn't help send me a mail

This could be a very big can of worms here! It should start with why you want to do this ... do you need to section off the groups for security or performance?

If you want more performance then a second network card in the server AND an ethernet switch would be a big improvement in bandwidth.

If you want to keep the two groups completely separate then a second card in the server and a second hub would segment your users.

In this case it would be easier to use 192.168.1.xxx for the first group and 192.168.2.xxx for the second - this gives you 254 addresses in each group and THE SAME subnet mask of 255.255.255.0 on all workstations (easier to manage).

As far as the server ... each card would get a IP address ... use 192.168.1.250for the first card and 192.168.2.250 for the second, using the same last octet keeps it simple too. Assign the address of the bigger group to the faster card to balance the load.

And lastly ... if you want to be able to get from one group to the other (maybe one grou

You can do as #2 suggests. However, if you want to implement a new mask, you can use 255.255.255.192 for the subnet mask. This will give you 2 subnets with 62 hosts per subnet. You would configure the subnets as follows:

Subnet 1 (first network card):
192.168.10.65
mask 255.255.255.192
hosts 192.168.10.66 - .126


Subnet 2 (second network card):
192.168.10.129
mask 255.255.255.192
hosts 192.168.10.130 - .190

This is a subnetted Class C network.

HTH,

Just a minor point: The reason all responses use 192.168.x.x as your choice(s) (versus the 191 you proposed in your question: The 192.168 subnet is set aside for use in "private" networks (behind a fire wall, etc.). Just in case you want to connect your networks to the internet in the future, do not use a 191.x.x.x network address at random.

The subnet mask 255.255.255.240 only gives you 14 hosts per subnet. From what you've described, you will need a minimum of 17 hosts per subnet. 16 users + 1 NIC in the Server.

If you use a subnet mask of 255.255.255.224, you can have up to 30 hosts per subnet. This would also give you a little room for growth. Using this mask also allows for up to 6 possible subnets, which means you could expand into other subnets also.

With this mask your first subnet would be 192.168.1.32. Which means your valid IP's would be 192.168.1.33 through 192.168.1.62. (you cannot use .32 or .63 as IP's in this configuration) The second subnet would be 192.168.1.64. Your valid IP's for this subnet would be 192.168.1.65 through 192.168.1.94. (can'tuse .64 or .95)

Give it a try. Good luck.
