portforwarding - Local portwarding not working with IP address but working when mentioned localhost

Question

I am trying to set up local port forwarding from my local to machine. I am using the following example to set it up

ssh -f -N -L [LOCAL_IP:]LOCAL_PORT:DESTINATION:DESTINATION_PORT [USER@]SSH_SERVER

There is daemon running on 2009 port of my remote machine. Assuming my remote IP is 10.0.0.0 I ran following to connect my localport to 2009 port of my remote.

ssh -f -N -L 2009:10.0.0.0:2009 10.0.0.0

I verified my local listening on port 2009 when i try to run lsof -i :2009. However when i try to run some command it says connection refused error. I also tested with CNAME of my remote, still would get same output: local would start listening but any command would throw connection refused error.
Also when i would use localhost instead of ssh server itself it would work perfectly fine.

ssh -f -N -L 2009:localhost:2009 10.0.0.0

Why is it working when i mention localhost but not when i actually mention the IP/CNAME of remote?
