Problems with JAIL in 4.8R

[stakys at punktas.lt]

Hi, i've set the outside ip for the jail..It works.. When i try to ssh to
jail'ed system from the main system (in which is created jail) the
connection is successful, but when i try to connect to jailed system from
anywhere else i get this message:
ssh: connect to host IP_NUMBER port 22: Operation timed out
What can be wrong here? How to solve this problem?
