Cisco: Setting a VLAN across a network
Basically as per your network topology & your point of thinking, first you have to make communication between router to switch means inter-vlan communication through encapsulation trunking on the router as well as on switch. On most of the cisco devices, dot1q encapsulation trunking is there, but you have to configure manually on the router. [...]

Packet Filtering information required
netstat will show you the connections in use and should also show you the PID of the process making the connection. You can capture at either location, but it may be better to span the client switch port to an analyzer port or hub out with an analyzer on the client link.
