Networking – route over multiple connections.

[Guest iskander]

On my laptop I am connected to a LAN (for work and internet). At the same time I use the dial up (t mobile web and walk plus through the phone, connected on Bluetooth). . I want to be able to use only certain services/destinations over dial up and everything else to be routed over the LAN. For example, set up one browser, a messenger, outlook to go over the dial up while all my other traffic goes though the LAN. How can I achieve this?

I thought of using some proxy server software to set up one browser to go over the dial up but how do I prevent everything else going over dial up then?

Cheers,

Dan
