ssh

I have 3 boxes set up as shown:

The DFW box can communicate to the SFO / internet just fine, and I send files AUS -> DFW. However, every time I trying transferring DFW -> AUS it fails over SSH (ssh client, rsync, scp, sftp, etc) with the following error:

Corrupted MAC on input.
Disconnecting: Packet corrupt

Occasionally I'll get a different error:

Bad packet length 2097180.
Disconnecting: Packet corrupt

I've restarted the DFW box, as well as replaced the network cable. I'm not sure what else might be causing problems.

Right now to get files from DFW I have to use DFW -> SFO -> AUS which is not optimal.
