this is the case of overlapping subnets, you are required to perform double NAT in this case

You can use either static routing or any routing protocols like EIGRP, OSPF etc.

But here I see that you might have typed a wrong network ID for the LHS LAN network. It should not be 192.168.1.0/25.

You also need to give a subnet network IPs between both the routers and run the specific protocol on both interfaces of both routers.

both routers are fully configured already  

 

Whoops, looks like something went wrong.
