1: Your PC needs to know how to get to the 192.168.10.0 network so either add a default gateway on it via 192.168.0.1 or add a specific route to 192.168.10.0 via 192.168.0.1.
2: Router 192.168.10.254 needs to know how to get packets back to your PC. Add a route to your network via the ‘10’ interface on the 192.168.0.1 router.
As the 192.168.0.1 router has interfaces on both networks it doesn’t need any routing table changes. Alternatively, enable a routing protocol such as RIP on both routers. You’ll need a RIP listener on your PC (or a static route to the far network).
