Can I have multiple policies on the same network?

Yes. There are a few ways to do this. You can implement separate subnets on your network and have DHCP hand out different DNS addresses to each subnet (we call this NAT IPs). We also offer a DNSFilter Relay software component/VM which you can use to specify different policies. Or you can set up one of our Roaming Clients on devices that you wish to have separate policies on.
