Image description of how it is setup
First Router is in 192.168.1.x series.
Second router is set up in 192.168.0.x series
The second router is setup in router mode, DHCP Forwarder. WAN IP address on second router is setup with an IP in 192.168.1.x series.
The users connected to second router with say IP 192.168.0.200, were not able to access internet.
Edit: The second router was needed since there are only limited IP addresses available from the First router and I do not have access to First router.
What are the options for me to extend the IP range without having to change something in the First router.
Edit 2: I think there was a slight confusion in the image I put through. Router 1 has internet access, router 2 is the extender. Router 2's wan port is connected to router 1's lan port. Router 2 WAN IP is configured as one IP from Router 1's series.
Edit 3: Added port forwarding options available on my routerPort Forwarding options on my router
