Superscope issue cant see initial scope

I have run out of IP addresses on my current scope 192.168.0.0 subnet 255.255.255.0 default gateway 192.168.0.231.
I have created a Superscope and a new scope within that 192.168.1.0 subnet 255.255.255.0 and added an alternate IP (192.168.1.235), using the same gateway (192.168.0.231) and dns settings (192.168.0.235) as the first scope, but when clients get a 192.168.1.x address, they cannot ping anything on the 0.x scope, or access the internet (due to not being able to see the dns server 0.235). ANy ideas please?
Thanks.
