Injecting traffic through one connection

Hi,

In my enterprise we have a new internet connection, that at the moment, is not being used. We want to test this connection before use it with scripting, injecting traffic to the external internet, and monitorizing it with the log.

I have made an script with pings, but I think that it’s not enough traffic to see it in the connection windows. And also the pings that I’m making inside the script are with the src-address option, but I think that the traffic is going out by the active internet connections (I don’t know if the only way to make the pings go through my “new connection” is to insert routes to the destination hosts ¿Is there any possibility?).

As the pings are being done o.k. althoug we don’t know the interface that’s been used, in the log I can see that the connection is working properly. But we don’t know it…

HELP ME PLEASE!!!

Ok, I solved my problem by myself, sorry if I disappointed some big brain ;D.
Now, I’m able to make what I wanted.
