ssh tends to play with TOS fields (and rightly so). Routing is keyed to the
*triple* (src, dst, tos), something that most people (including me) normally
forget. However, in this particular case that may be the reason for your
ssh's breaking.

The reason for FTP breaking possibly has to do with packets for
the control connection going out the one gateway and for the data going
out the other... but this is speculation on my part.

Doei, Arthur.
