SSH connection hangs on shell commands when used through tinc

[Viktors Žilinskis]

Hello!

I have 3 PCs - Windows, FreeBSD and Ubuntu. FreeBSD runs as a tinc server as
it has a real IP. Ubuntu runs as a tinc client as it has a dynamically
changing public IP. Windows has not tinc installed yet. Therefore I use
Putty ssh client to ssh to FreeBSD machine (as it has real IP) and then from
there I ssh to the Ubuntu box using its virtual IP. The connection
establishes well, I can ping FreeBSD and Ubuntu virtual IPs in both
directions, no problems so far. But when I use any shell commands which have
significant text output, the ssh connection just hangs. For example, if I
list files in a small direcotry (5-10) it lists them, If i list a bigger
directory it hangs. It also hangs on other commands, like top. Interestingly
enough, I tried to do that in the opposite direction - connected via ssh to
FreeBSD box virtual IP from Ubuntu box, and I could not find a command which
could hang the connection.

I've tried to use different ssh clients, but this does not help. Though I am
not sure, I think there  should be something wrong with my tinc setup.

Any ideas?

Best Regards,
