Internal DHCP server on Aruba controller is not supported past 512 concurrent leases, so, as long as you are in that scope, you should be fine.
To set this up, create a new VLAN, assign an IP to that VLAN interface that would be the guest clients default gateway. You then need to enable DHCP server on the controller (service dhcp) and then create a scope that matches the subnet you configured on the VLAN interface. Once this is complete, map the Guest Virtual-AP profile to that VLAN ID and you should be good to go. If this is a non-routable subnet, you may want to enable "ip nat inside" to that VLAN interface.

I have dhcp setup and I have a vlan of 100 applied to the guest access network. I'm getting a good ip but I'm no longer getting the captive portal page. It is a routable ip block that I have added to our core routers. Any thoughts?

Is DNS able to resolve? If DNS is not working, then the CP will not open automatically. Try opening a broswer to "http://18.104.22.168", if CP opens, it is a DNS issue. Are you nat'ing VLAN 100? If not, enable IP Nat Inside on the VLAN 100 interface or ensure that VLAN 100 is routable.
