Hello,
I assume that you have verified that your problem is not caused by any ACLs in place.
What does a traceroute or tracrt command say when you perform it from a host in the 10.0.0.0 network towards a station in the 192.168.0.0? Where does the traceroute stop?
Are the stations in both networks aware of the existence of the other network? In other words, do the routers in the 10.0.0.0 network know about the existence of the 192.168.0.0 network, and vice versa? It may be possible that either the routers are unable to route the packet from 10.0.0.0 to 192.168.0.0, or that the reply back from 192.168.0.0 cannot be routed to the original sender in the 10.0.0.0.
As you can ping all stations in 192.168.0.0 from the router itself, this seems to me to be a routing issue. Please verify that all routers in both your networks are aware of the existence of all networks.
Best regards,
Peter
