capture all proxytunnel output to a file

Question

When I use an ssh command with proxytunnel I always get an output like

 Via xxx.yyy.zzz.aaa:pppp -> bbb.ccc.ddd.eee:443 -> remotesvr:22  

before I get the output of my command

I want to capture all output to a file including the "Via ..." stuff.

As an example using the *ls* command I tried

*ssh remotesvr ls 2>&1 > $TMPfile*  

but the Via xxx... line still gets to my terminal instead of $TMPfile.

How can I get all output captured to $TMPfile?
