problem with opening closed port

[latadeyek]

how do i open a blocked port in mandriva using shorewall.i have tried it using iptables but it still did not open.please i need suggestions

Hi - Which port are you trying to open? Shorewall has its own configuration file buried somewhere in your directory tree. In there you can specify which services the firewall allows.

Actually, what I want to achieve is this. I have two network cards on a mandriva 2006 server, one is configured for the local network and the other for the internet. I'm streaming videos using a video camera and the streaming is done on ports 1720, 16384,16386, 3230:3235. I'm able to view the streaming with the local network but systems connected to the internet(i mean to the internet interface were unable to view the streaming. I tried without firewall but i don't know how to open ports. I tried opening the ports using shorewall but nothing happened. I tried viewing the opened ports on my server using nmap command, and i discovered the ports are not among the opened ports.

I will appreciate if u can help me out.
