to open up ports, use port forwarding. what you do is set the local ip address for ex. in your case 192.168.0.x (x being the number of the system you are trying to open the port to) then for the starting port and ending port, you put the port number for ex. 21 (ftp port) if its just one port, you put that port number in both boxes. if you have a range of ports, you do for ex. 20 for starting 21 for ending. therefore, you have a range of ports 20-21. for protocol, usually its TCP but if you dont know, use TCP anyways. if there is an option saying both and you dont know, use both. then check the box to enable your setting. that should do it. good luck.
