I am scratching my head here. I now get timeouts between hosts
B, both running Ubuntu, with some firewall NATing on either side and a good dozen hops in between. (To clarify based on the first comment: The initial connection fails and 'hangs'; this may be after another (existing) connection ended.)
Yet I can also connect using ssh from
A to another host on another subnet, call it
C and then connect from
B just fine. So it should not be the ssh server settings. The alternate route also works for a second host
D, also on another subnet.
But the trouble is that my main workstation often just sits there when trying to connect. The only related issue I can think of is that I am also (sometimes) using
sshfs between A and B.
One idea as to how I can address this?
