Second network

Nigel · 25-04-2008, 11:40 AM

In my office we have a server connected to the internet. We are now setting up an IT training room with 12 PCs, with which we intend to create a stand-alone network. Can i use another router/modem for this network which will be hard wired, using the same ISP connection details as the original network .

Hi,

I believe this is something that you can do. You would need to give your new router an ip address on your main network like any other device, and then just set a new ip address on a different subnet inside the router for the new network. For instance, say your main network is 192.168.1.xx. Let your router have an ip address on that one, like 192.168.1.100 for example. Then configure the internal ip address for the your new subnetwork on the new router to something like 192.168.10.1 so that your router will act as the gate way for the new 192.168.10.xx network. Its something we talked about in class but I have never had the chance to try it out though, but it should work

Depends on the ISP; some will let you have multiple IPs with the same account. For instance, mine provides 5 IPs. But in any case, you can not use the same public IP address in two places at once. So, you won't be able to use exactly the same settings either way.

If I was in your shoes, I would build an IPCop or pfSense firewall with at least 3 interfaces, and put the entire network behind it. You could put the production network on one subnet, and the lab network on the other. They would be physically separated by the firewall, yet share the same internet connection. (I can draw you a diagram if you need more clarification.)
