Yes, if a firewall were blocking it, you would get a "Connection
refused" instead of "Permission denied".

If you are using TCP wrappers on ssh, remove that.  If you don't know
what that means, you're not doing it.

Try adding the "-v" flags to sshd, not just the connecting ssh.  To do
that without rebooting, I think you need to kill your existing sshd
and run it again from the command line.  If you put 'sshd_flags="-vv"'
in /etc/rc.conf, it will be done automatically at every boot (until
you remove the line again).  I think that the debug messages will go
into /var/log/messages.

Good luck.
