Changing rules of ip routing

[smss]

Hi everybody,
I have two network with three connections:
1th. Wireless Connection. -> In order to connecting to WorldNet [Name: ra0]
2th. Wired Connection 1. -> In order to connect to other computers ( may be remote virtual computers ) [Name: eth0]
3th. Wired Connection 2. -> In order to connect virtual computers directly ( set the Virtual Box settings to Bridge to this )[Name: eth1]
Now, I need to connect to my virtual servers through eth0 locally as I connect to WorldNet through ra0.
In other words, I want to browse local virtual servers and worldNet at the same time.
Note that I have changed wired DHCP ip begining and getway to 192.168.2.2 and 192.168.2.1 respectively.

Thanks in advanced.

Ok, I Solve it.
Just by

 ip r

I see to how ip r work in different situations and I replace the default routing row with this code

sudo ip r change default via `IP` dev ppp0  proto static

and it solved.
Thanks in advanced, smss!
