Separate networks

Is it possible to divide 2 networks that would be using the same router to access the internet?

I have a similar setup to this diagram. The problem is i have no access to the router so can create the 2 VLANs but not the subinterfaces.

There is only 1 way to do it without having access to the router. You would need a Layer 3 switch with IP routing enabled. Then you can have your 2 separate vlans, then one vlan to go up to the router.

Edit: Sorry, there is a second way. Another router between the switch and router, with NAT.

I didn't explain it very well. I have one network on the switch (not a vlan as unmanaged) which connects to the router. I have access to 2 2950 switches if needed. I want to create a second network as the aim is to be able to connect a router to the network to test it without it effecting the other network.

Without access to the router, there is no way to add a second network without affecting the current network. All traffic to get to the router would have to pass over Vlan 1 (native vlan) which is what all devices on the unmanaged switch will be in.

I expected this limitation to have a big effect on what i needed to do.

Thanks.
