 I guess that I need to reestablish the route.
 How?


No, that is an indication that port 22 is not open.

No.  That error is from an ICMP message and means exactly what it
says.  It has nothing to do with what is or is not listening on the
remote host since the attempt to connect to 192.168.1.12 never got
that far.

You do not have a route to 192.168.1.12 from the host that you
used to run the telnet command.
