Connecting network

Hi,

We have an existing network with a switch and a few servers connected to it. Now we are going to have a new network with a broadband modem for connecting to the isp, a router that connects to the modem and a switch which the router and new workstations connects to.

Now we need to connect the 2 network together because the workstations will need to talk to the servers on the seperate network. At the same time, we would like to give internet access to the workstations.

The 2 networks work fine when standalone but when we try to connect the 2 networks together (see attached diagram). The workstations are not able to see the servers. The router has got dhcp on.

May i know what ip ranges and subnet i should assign for the new network so that it can be on internet and at the same time able to communicate with the servers on the existing network.

thanks

If you can, use the same IP rages and subnet as the original network.
If there is only one device performing DHCP it should give out the correct config to the new PC.
The new server (probably static IP) will need to be configured for the original network as well.

Agreed. Just make one network subnet. Unless there is a reason to keep the new workstations from talking to the old workstations.

Your diagram only shows one server?

Your servers should have static ips. So just block that in the firewall.

I agree with these answers.

If you use different subnets you will need a router (or some layer 3 device) somewhere to allow the 2 subnets to communicate with each other - either using your existing router or another router in between the subnets.  That router would need to control / block your servers from the internet anyway.  You might as well just keep everything on the same subnet and block them with your in-place router as stated above.  

Sometimes simplicity is best.  

Another option is to set a static IP of 127.0.0.1 for the gateway on your servers and that would also prevent them from accessing the internet.
