Changing Subnet of DHCP users

[asistio04]

How can i seperate all my guest to my existing subnet in dhcp?  i am using a captive portal for authentication, so that all unidentified connection will be on the dhcp how all dhcp user will not see any computers on my network.there are no option in the dhcp server on changing a subnet

can i create another interface and i will use this new interface as a gateway in dhcp server?

You put them on a different network (interface or VLAN) and configure that interface or VLAN accordingly. You don't change subnets in DHCP on a single interface, you setup a separate DHCP server instance on a separate interface or VLAN.

Is this possible not adding 2 new NIC cards?  Meaning, there is an area in the GUI that I can create a new DHCP instance, create a new subnet range and tell the router to use this 2nd one instead of the original subnet range?

I'm working with one that is on a 1.x range, I need to change the range to 50.x
