We're running a FritzBox from our DSL-Provider in front of our TP-Link router. Now we want to use the DHCP-Server of the TP-Link, so all clients get a IP of the range 192.168.0.0/16. But we also want to access the 192.168.0.0/16 network from our FritzBox 10.0.0.0/24 network, so all clients in this network can access the clients in the TP-Link network, without port forwarding or anything else.
What is the best way to achieve this? I already tried a static route in the FritzBox, but it isn't possible to access the clients behind the TP-Link:
Network: 192.168.0.0
Netmask: 255.255.0.0
Gateway: 10.0.0.2 (The TP-Link IP in the Fritzbox network)
Here's a diagram of the network structure: Network Diagram
