I have a "guest" company moving into a room in my building. The room is on the far side of the building from where my ISP connection is. Pulling a wire would be extremely difficult. I have one network port in that room and it goes to a secure room.
My existing lan is configured 192.168.1.x. I am planning to put a router on my ISP modem and assign it a public ip and set its lan to 192.168.20.x. On a second router I will connect the port from the room to a lan port on the router with that routers lan set to 192.168.30.x. Then configure the second routers wan as 192.168.20.X.
I believe this setup would allow the guest traffic for internet but would prevent them from accessing my 192.168.1.x lan.
Is there a better way to isolate the guest without running new cable?
