When you try to connect to 192.168.0.10 from 192.168.0.61, connection won't happen, because 192.168.0.10 belongs to the same logical network (192.168.0.0/24) as 192.168.0.61, and but since 192.168.0.10 is not physically present in the 192.168.0.{61-110} network, ARP fails, therefore no connection. You need to create route for 192.168.0.{10-60} to route via 10.81.0.25 in 192.168.0.{61-110,111-170} and similarly for others also. Also you need to add these routes in the 192.168.0.{4,5} . Instead of assigning 192.168.0.0/24 network for lab PCs, assign /26 addresses. I think you need to redesign logical network.
