If it asks for the password, it is not a firewall issue.
Are you attempting to log in as 'root'?
If yes, try using another username in the
target computer. Pretty many SSH installations
disable direct log in as 'root' for a good reason,
DO NOT CHANGE IT!
To get in as root, log in as another username
and use su or sudo to gain root access.
