Need to open all ports in Linux Firewall (IPCOP 1.4.21)

Hello,

I am needing to open all the ports on my Linux Firewall (IPCOP v 1.4.21)

Basically I am now using the Linux Firewall (IPCOP) as just a DHCP and for the traffic reporting.
And I have put a hardware firewall in front of it for protection.

Is there a way to open all the ports in Green & Red networks on the IPCOP v1.4.21 Firewall?

Thank you in advanced for helping me.
Anthony

its call forwarding
you need to forward all the ports you want from ipcop to the pc you want to one by one

there is not any point of openning all ports, when you need only few

example 80,25, 22

can i know what you meant by openning ports to every pc ??

i have doubt about that to open all ports ..

but you can try 2 things

1. stop firewall totaly in icop
2. edit /etc/rc.d/rc.firewall.local and insert your own rule

read this, user customization

What I'm finding is i cannot connect to an extenal ftp server using ftp Port 21 or SFTP Port 22 from any of my pc's behind the IPCOP green network.  However when I take a pc out of the IPCop and put it directly on the internet, I can access the FTP server.
How should it be configured in IPCop to allow all the pc's on the green network to connect to the external FTP server which is located on the internet.?

Yes I have those settings under the destination ports
"Allowed standard ports"
I also have Enabled on Green with a checkmark
and Transparent on Green Checkmark
I have clicked on the save & restart button.

Still to no avail.
