Hello, I am trying to figure out the best way to create two separate networks using one external IP address. I don't want the networks to be able to communicate with each other. I read about cascading and also read where you get a 3rd router and connect two routers to it. Taking off DHCP and assigning static IPs. Not sure the best way to go about this and any input from you guys on the most secure way to do this would be most appreciated. You'all never steer me wrong.
