IP Setting

The 192.168.1.1 is a private address (not routeable over the internet). The 10.130.141.1 is a public address (routeable over the internet).

If you want both computers connected to an NT server, you need to purchase a hub or switch.

If youdon't need the internet... set one ip address to 192.168.1.1 (the server), another with 192.168.1.2 and the third with 192.168.1.3. All three computers should have the same subnet mask of 255.255.255.0 and all three computers shlould be in the sameworkgroup or domain.

If you do need the internet, then instead of a hub or switch, look into a broadband dsl/cable router and connect the computers and the server to that. You can still use the 192.168.1.1-3, your broadband router would need another ip address on the lan side 192.168.1.10 and a routeable ip address on the wan side (the 10.130.141.1).

Ok, we will assume that each group is on it's own cabling scheme with a hub or switch. Both IP ranges are private IP addresses (networking 101)
10.0.0.0 network includes all addresses from 10.0.0.1 to 10.255.255.254 with a subnet mask of 255.0.0.0 This allows you to have over 16million IP addresses on a class A subnet. The second range of addresses on the 192.168.1.0 network will allow you to have 192.168.1.1 up to 192.168.1.254, thus giving you only 254 hosts. Both are private! If you only wish to have them connect to one server and nowhere else, have two network cards in the server, one configured to the 10.x.x.x network and the other going to the 192.168.1.x network. If you would like these two separate networks to access the internet then a third network card in the server is required, this one will then point to your router to the outside, the other two network cards will then point to this one as their default gateway.
Good luck!

Hello there,

Are the 2 groups in the same location (building)?, is the answer is no, then you have to configure a VPN connection, that's another history. If they are on the same building you have 2 options, if you go to Control Panel, network adapter, TCP Properties and click on Advanced you will see that you're able to add more addresses to the same Network Card, just make sure it binds 2 addresses, one for each group and it will work. The other option is add a second network card to your server and give it a valid ip address on the other IP range and it will work, I think the second option is the best since that way you'll reduce the traffic on only one adapter.
If you have 1 hub per range, I mean 1 for 192.168.1.x group and another for 10.130.141.1 group just link them together and just follow my previous steps.
It should work.
