How to link two networks with different IP ranges

  • 772

I've got a network on ip range 192.168.0.X. It has a router with an internal IP on this range that lets it talk to the outside world.

If I create a new network on ip range 192.168.1.X. How can I get this network to see the first network on a different IP range and more specifically the router on the original range.

The computers are windows and linux based.

  1. Your options depend on just how capable your "router" is.

    Option 1

    If the router is capable of assigning multiple IP addresses to it's internal interface (or has multiple interfaces) then you should be able to assign it both 192.168.0.1 and 192.168.1.1 (assuming default gateway for both networks is xxx.xxx.xxx.1)

    Option 2

    Pick one of the Linux machines on the network, assign it's interface addresses out of both ranges e.g. 192.168.0.15 and 192.168.1.1 then add a static route to the 192.168.1.0/24 subnet on the router via 192.168.0.15 and enable IP forwarding on the Linux machine.
