Accessing device on network with different IP Range, RB750UP

I have an RB750UP setup, it has the PoE so I have it setup for a wifi network with 3 wireless APs.
The DCHP Server is on IP Address 192.168.88.1/24, everyone that connects to the wireless gets assigned an IP from that IP range.

But, I have connected a device to the network, which has a static IP of 192.168.2.20. I can’t access that device when I connect via DCHP, and get assigned 192.168.8.*

If I set MY ip to static, and set it to 192.168.2., I can access the device at 192.168.2.20. How can I setup the router to access 192.168.2.20, when I am on DHCP at 192.168.8.


My goal is to access this device remotely via the internet as well.

The router needs a route to get you there.

Assign 192.168.2.1/24 to the interface that it is plugged into. Then the router will build that route into the routing table and you can reach the device from the other network.
