Sounds like split-tunneling is not enabled. This is a setting where you can be connected to VPN and access services on the local LAN simultaneously. Many VPN solutions are configured to deny split-tunneling.
Since your system has an IP address on the VPN network and the local network, the default routing is also confused. You could set a route to the 10.200.x.x network using the default router for the 192.168.x.x network (if that is where the routing to the 10.200.x.x network happens).
