Open Ports

Does anyone know how to open ports from the command line? I have a firewall instalelled on a remote compuer. The way i can acess it is only throught SSH. Lately I installed TightVNC on it through SSH, but the firewall does not let me connect to it somehow. All i can do is use the command line, and i dont' know how to open ports through command line. Google didn't help much either. Can anyone help me with this? Thank you...

read "man iptables"

the quick answer would be....
Code:
/sbin/iptables -I INPUT 1 -p <protocol> --dport <port_Number> -j ACCEPT
rpeplace M<protocol> with wither UDP or TCP, and <port_Number> with the port you want to open.

this will inrt the rul to allow this traffic at the very top of the input chain.
