How to add more than 1 IP .... ?

Hello Everyone !

A little help i am seeking for. I am running Mikrotik version 3.3 stable from few months as a hotspot. It is working good, but now a need arises that we want some of our customers to be connected without any authentication. For this i added another Subnet on the same Interface that is already serving hotspot clients, also added the new pool under IP>Pool and also added a NAT rule in Firewall to NAT the new subnet.
But now as i assign the new IP to any of the client they are also getting the hotspot login page instead of getting internet directly. Further i want to create several small subnets /30 on the same interface.

Your response will be highly appriciable.

Thanks

I think you are wrong here, here we are speaking about The Gigabit Switch with SwOS (ATM only R250GS).
