Actually my fiber connection has a smaller limit than the ADSL 
connection. I am trying to use the fiber connection for all activities 
except some torrent downloading for which I want to use my ADSL 
connection.
Once I'm able to route through the ADSL gateway, it would be easy for 
me to setup another ip on eth0 on my machine on which transmission 
could listen. All traffic on that ip would be routed through ADSL and 
otherwise the fiber.
