Help needed in Win7 complex networking (defining routes)

Folks,

I will need some help in setting up my Win7 networking.

I have a LAN connexion to the local network that does not allow Internet access.
I have a wireless (3G) access to the Internet.

Although I'm pretty sure the network admin won't really like this I want to be able to use both accesses at the same time (without routing, obviously ;).

At the moment here is my IP config when being connected on both adapters

(BTW I will also need to route 10.150.7.0/255.255.255.0 to the local net)

I can connect to the local network but not to the Internet (Internet bound packets are routed to the LAN)

Any advice as of what (presumably static routes) I should do to achieve "double connectivity" ?

all you may have to do is in the adapter properties ipv4 advanced tcpip settings is uncheck the automatic metric and give your 3G adapter a lower metric say 100 and the LAN 200
