So,the situation is like this:

I have 2 routers of 2 different ISP(each respectively),one is connected by Wireless,and the other by LAN(cable).

I want certain applications to use ONLY connection 1 and the rest to use connection 2:
eg: Firefox to ONLY use connection 1, others use ONLY connection 2.

Is it possible,and if so,how do I do it?

more info:
-Running on Desktop PC, Windows 8.1 64-bit .
-Network driver : Realtek PCIe GBE Family controller


Thanks!
