I am connecting via RDP to a Windows 7 Professional machine. I use that machine for its data/programs, but at times I also need to (within the RDP connection) connect to a VPN (configured via L2TP/IPSec), not on my client.

The problem is the VPN seems to take over all traffic, so I then lose my RDP connection.

What sort of network configuration (I'm thinking virtual adapters of some sort or the routing table) could I use to get around this?
