do you mean like telnetting from one system to another and then downloading and expecting it to cross both telnet hops?

if yes, i would first be looking at the connection between the two servers and seeing if it is a binary capable stream or not... if it is not, is there an attempt to switch it to being so? whatever the client passes to the
first server might should also be passed to the second server so channel switches like this can take place...

if this switching is being sent to the first server but not passing on to the second one, well... i dunno... could be a security thing or just a defect... or maybe even a policy thing... more research is needed ;)
