You can also use telnet to check for open port if you know the port number
from putty/shell - telnet to the port you want to see if its open

these are nat rules .. you dont need to open ports on the router to make these work
have you configured these? what is the issue?
have you configured ip nat inside/outside on the interfaces?

show ip nat translations
use putty and telnet to the ip and port you want test if its open.
or you can use a port scanner like nmap to see what ports are open
