Splitting one physical network into 2 seqments making sure each side cannot see or get to the other
I have a business that need to have 1 physical network split into 2 segments. They each have their own Server, their own SonicWall firewall where DHCP is handeled. Each has internet access coming through seperate cable boxes. Each has it's own swich with their own pc's plugged into their own switch.
The problem seems to be there is one resouce, a network printer that is in one of the two domains.
I need to be able to have Company A point to Company B's network printer.
Also I have not turned on DHCP for Company A, so they currently get DHCP from Company B's SonicWall. When I do turn on Company A's DHCP server how can I make sure that Company' B's DHCP server won't send leases to Company B. And yes do to the network printer the switches are currently connected.
What are the switches that you have? and what are the sonicwall FW types? IF you have switches that support VLANs, you could split these segment over 2 VLANs. If you do so, you can then put the FWs in each segment to perform the DHCP and FW function to the internet. To route between these segments (for the printer to be reachable for company A), you would need a router with 2 ethernet ports.
If you let me know the exact types of switches, (routers if you have any) and FWs, we can go more into depth on how to configure all this.
